Email - error connecting to server

RouterOS General
1

Configured email server settings, getting the above when sending a test email.
No Firewall rules to prevent this, and email server is on VLAN connected to my RB750. Other external and internal clients using the mail server normally. Router can ping/traceroute the IP address without an interface specified.
Error is exactly as above - no indication of authentication issues etc although have allowed the LAN IP address of the RB750 as allowed to use mail server as a relay so should bypass authentication process.

Any suggestions? I’d like to get this working for email of log etc.

What is the mail.log of the mail server when mikrotik tries to send email?

3

Nothing at all - doesn’t appear to be reaching.it.

4

Enable debug logging for email, then try the email send again and check the log.

/system logging
add topics=e-mail,debug action=memory
5

Tried that, only got the same as per thread summary.

6

Can you ping the email server ip from one of the computers that can’t connect?

7

PCs are fine, just ROS is the issue. Can ping IP no problem.

8

Does that mean you are trying to send an email from the router? And you added the debug logging to “/system logging” and nothing shows in the router log?

9

Correct trying to enable ROS email function.
Tried internal mail server and gmail.
With debug level logging all I get is error connecting to server. No further info.

10

Then the router is unable to connect. That is usually a firewall problem on the server. Check your settings there to insure it allows your localnet to access that port.

11

No fw running on server. No issues inside LAN (any VLAN) or from WAN with any other smtp access

12

Then check your email setup in the router to insure you are using the correct port and security.
/tool e-mail

How are you trying to send the email? Are you trying from the command line or from a script?

13

Setup is exactly as per working mail clients.
Using System/Email in Winbox and using the sent test message option

What version RouterOS are you using?

Mine is under tools - email, and my email test was in my inbox first try. I am using ROS V6.5 and Linux with Sendmail as the smtp server. And the same router sends me a voltage readout for the last 24 hours every day.

I have in the past tried sending to my gmail account and it works also.

I tried to send through one of my servers that does not accept port 25 email, and I got a message in my log like this. It took a minute or so to show up in the log:

Dec/26/2013 18:08:07 system,e-mail,error Error sending email : abnormal termination [timeout]

Edit: Thought I had it sorted, but I haven’t.
Getting further than before but still no success. Getting a timeout, but don’t understand why as no internal nor external client has any issue connecting to my mail server.
