Hey guys, I know this is been up alot before, but I am out of options. I have a 7200 that is setup to go to DynDNS (some hosted outgoing email provider). They only use the username and password to authenticate, I keep getting a 501 reply, (which i understand as the the remote end not authenticating me). I have also used several different ports with the same result. I used Samsungs test SMTP account, and it worked great. The guys at DynDNS cannot watch the server in real time, like samsung does. All they keep telling me is that they do not see any errors on their end. I asked them "If I cannot get authenicated on your server, do you get the failed attempt from me on their logs, they said no" Anyone ever use this company before. Thanks in advance for any help with this.

I'm assuming this DynDNS is giving you a static pub ip address for the smtp? Have you tried not using a username and password, but instead only configuring the smtp server address? I was having similar issues trying to authenticate to a customer's ISP, but instead found success in not tryin to use a username or password.

501 is 'Syntax error in parameters or arguments' for SMTP connections, you might have to resort to looking at the network traffic with wireshark or similar to see what's going on.

DynDns is a dynamic DNS host, I didnt know that they hosted mail accounts. Doesnt the ISP you are connected to have an SMTP server? Thats all we use down here. For example, if my ISP is TPG, then I use smtp.tpg.com.au (or usually the actual IP adress), if its Westnet for the ISP, then its smtp.westnet.com.au (or the IP adress) etc.

Can you send email from your laptop when connected to this network?

I had a differnet scenerio and it was on a 7100 but none the less I was getting 501 errors yesterday and it ended up that port 443 on the router was not not forwarded.

Sending email out has nothing to do with a port being open for inbound traffic.

Anyone ever installed the freeware Sleepwalker SMTP server. Just curious how that has turned out. Thanks.

I have used 1st SMTP server and it worked great. They have a free trial.

I have used main enable, the standard version is free, i used it to get around the email gateway bugs in the 7030 and 7100 where the smtp server isnt on the same lan network as the system.

I have used Sleepwalker (for the same reason as nameless) and it ran fine in several sites until we got a later software version that now rectified the promblem.

Just curious if anyone has ever got this to work with yahoo, gmail, or hotmail.

You can send to yahoo, gmail and hotmail accounts, but you cannot send through these mail hosts.

I'm not sure why everyone is having so many problems with the e-mail gateway. If your customer has high speed internet, most ISP's will provide you with a FREE e-mail account and most ISP's have SMTP servers. Even if your customer has their own domain, you do not need to send through their mail server… you can use any SMTP server.

For the e-mail gateway to work, the voicemail only needs to send the e-mail to an SMTP server. Setting up this feature does not require the opening of any ports in firewalls.

We had software issues with timing out when sending to some ISP's SMTP servers down here Marc, not sure if you guys got the same versions over there or not.

At the time, a temp fix was to bounce it via an SMTP gateway like the Sleepwalker proxy then out to the ISP's servers.

Marc,

Here is a scenario that I have at my bench. I have a 7200 with a dsl. The dsl is through ATT. I have an email setup with them, but in order to access it, I have to goto yahoo mail and login with my att cred. ATT uses yahoo mail, and the VM keeps saying " connect to server timed out" I am running 4.30i, don't know if there were any issues with this or not.

Contact AT&T and ask them for information regarding their SMTP servers. It's the same as setting up Outlook on a PC... you need to enter a valid SMTP server to send the mail. There is one caveat... you must use IP address... you cannot use the domain name for the Server.

Checkout this article regarding setting up Outlook on AT&T DSL. I didn't read the entire article, but it looks like what you need.

Ironhedz,

After reading the above article, I think you will get it to work if you do the following:

For Host ID, use the IP address 66.196.96.87. (I got the IP address by pinging smtp.att.yahoo.com.)

For Port, use 465.

For SMTP User ID, use your full e-mail address.

For Password, use your password.

IMPORTANT: For Domain use whatever follows the @ in your e-mail address... most likely yahoo.com.

You need to do this in BOTH System Wide Parameters and MClass.

After making the correct additions to your subscriber, go Port Activity and watch what happens.

Marc,

I just tried what you suggested. I get "SMTP Connect to Server 66.196.96.87:465 failed. ReplyCode -1"
cannot find what this reply code means anywhere.
The email address is something like this [email protected] - any more suggestions. Thanks

Change the Domain field in both System Wide Parameters and MClass to sbcglobal.net.

Ironhedz,

Okay... I got it to work for you using the e-mail and password you sent me via PM. Even though AT&T says you need to use port 465, it doesn't work. I changed it back to port 25 and it works.

Try making that change and let me know.

Marc, were you using AT&T in your test? Most ISP's down here block port 25 for anyone other than thier own SMTP servers.

I am not sure what you mean by a test. He sent me his login credentials and I setup one of the voicemails in my lab to use his ISP’s mail server. I think everyone is getting confused and it's not helping by posting things you do not know about.

If your ISP blocked port 25, you would not be able to send e-mail. Maybe they block port 25 for inbound traffic so you cannot run your own mail server, but that's not we were discussing here.

As far as the problem Ironhedz was having, he could not send out using the SMTP servers provided by his ISP. I looked up the necessary information for his ISP and they showed they used SSL for SMTP and he needed to send using port 465. As it turns out, the information I found was out dated and he needed to use port 25.

For those that have posted about opening ports and ports being blocked, that only applies to traffic that is coming into a server. The SVMi E-Mail Gateway uses SMTP to send the message.

Based on some of the replies here, I think many people have a misunderstanding how this works.

So... what is SMTP? Short for Simple Mail Transfer Protocol, SMTP is a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another.

The messages can then be retrieved with an e-mail client using either POP or IMAP. In addition, SMTP is generally used to send messages from a mail client to a mail server.

In our case, the SVMi is the mail client that is sending the message to the SMTP mail server.

Just wanted to say thanks to Marc. He took time out of his day to help a fellow tech here on the board. I can't say how much this was appreciated. Marc if there is anything I can do for you here in the Ohio area give me a shout. Thanks again for all of your help on this issue.

Your gonna make his head swell even more than it is now.....
All kidding aside, Mark is top notch around here. Thanks for the praise report its always good to have members with positive input.


GOOD JOB MARC!!!!!

Good Job Marc.

Is this a problem caused by Samsung not supporting SSL?

Hi Marc, port 25 blocking on outgoing SMTP connections is exactly what I was referring to, not by the router but by the ISP.

It is also something I actually do know a lot about, being very well versed in IT, and the IT manager for many of my customers when wearing my other hat. Maybe outbound blocking of port 25 for anything other than the ISP's SMTP servers is something less common outside of Australia? It's done down here to reduce spam supposedly.

Down here, every ISP that I am aware of only allow outgoing emails via port 25 through their own SMTP servers. So, if I have BigPond as an ISP, I have to set up the SVMi to use 61.9.189.249 (BigPonds mail server address) as the address for the outgoing mail, with no user name or passwords required. If I use anyone elses SMTP servers I can not use port 25 as it is blocked.

Thats what I meant when I asked if you were using AT&T as well for an ISP when you setup the Voicemail to use his ISP's SMTP log in credentials on port 25.

If I were to try it down here using his ISP's SMTP server and log in credentials on port 25 it would fail everytime, on every ISP I could try since I do not have access to an AT&T service.

I can use different ports, for example I can set up using googles gmail SMTP servers for the outbound SMTP server, since gmail uses port 587, or any other external private or public SMTP server that supports ports other than 25.

Hope that makes sense and clears up why I was asking the earlier question.

Thats what I meant when I asked if you were using AT&T as well for an ISP when you setup the Voicemail to use his ISP's SMTP log in credentials on port 25.

Okay... I apologize for the misunderstanding, there was another post above that mentioned opening ports in the router… so that's what I thought you were talking about.

In the states I can't think of any ISP that is blocking port 25 for outbound traffic. In the latest setup above, he was using AT&T for both an ISP and for the SMTP server.

You mentioned Google uses port 587... so am I safe to assume you have had luck sending through their SMTP servers? I have not tried because I haven't had the need, but I am sure there are others here who would find the information beneficial.

Hi Marc (and others...) I was using the gmail as an example, and in thinking about it, it would be a good idea. I jsut tried in the Dungeon (my work areas nickname) but I get back a response that the login is not supported, so I guess unfortunately it was a bad example to give!

A better example would have been using an externally hosted exchange server on port 465, I have done this before with no problems.

Hi

I have never been able to get Email Gateway working here on our 7100 I gave up in the end. So after reading the post I though Id have another play. And now it works!

We are sending to the public IP of our externally hosted exchange from a valid company email to another valid company email account.

I didn’t make any changes but log into the voicemail and change the port from 25 to 465 in both locations. This didn’t appear to work so I changed it back to port 25. Anyway a couple of minutes later I got the message sent on port 25 and 465. Could have been that one message sent on 465 prodded the mail server and now it accepts mail from that email address on port 25.

Strange as this mailbox had been attempting to send on port 25 once or twice a day for 6 months or longer and failed delivery.

The VG Key still flashes even if the message has been delivered via SMTP little strange...

I thought it was ok but upon further testing the EMG would only work correctly if called from the “office” extension. It seems to be something to do with how the system is presenting the email to the exchange server. And as you can see below I have somehow gotten it to trust messages from the office extension.

So how do we come up with an arrangement so that the exchange server will accept all emails form the EMG?

I have tried authentication in the past but this doesn’t seem to make any difference.

I don’t think I ever got this email though...

Jettech what firmware are you running on your OS7100?
you need to get hold of 4.30l, as I believe the ERROR - non_blocking_connect() failed is the error you get with sending email to a smtp server outsite of the local LAN with firmware below 4.30l on the MP10.
The MP10a didnt have this issue, or so im told.

It is running 4.41c now.

I don’t remember ever upgrading the voicemail file on the MP10. I probably have the same one since 4.07 Is this important?

Was running on 4.30 A-K for a fair while when I first tried to get it going.

I do have the option to send to a private IP as we have a VPN tunnel to the mail server which our PC's all use. I couldn’t get it to work on private either so that’s why I started sending to the public IP.

After looking at the activity log some more I am sending every time on port 25 its what the mail server does with the message due to its presentation of the email address. One would think the email address should be consistent form the EMG and the subject is the only thing to change.

The ERROR - non_blocking_connect() message was when I tried to send on port 465 so I should rule this out.

So in this case I think the issues were:

Possible problems pre 4.30l / 4.4 sw as I don’t recall getting a sent response in the activity log on 4.30 K and before.

Once I had upgraded form 4.30K to 4.4 it started to work but mail server started blocking due to presentation of sender address

Still dont have fully working EMG but should be able to come up with a solution with our ISP

Make sure you set the reply to and error email address' in the system wide paramaters, as it actually uses the reply to email as the from email address rather then what you put in the mailbox from field.
whilst on that screen make sure you set the timezone correctly, had a customer complain that a message took a couple of days to get through and it turned out to be a incorrect timezone setting on that screen
