SMTP mail server issue in Emailgtw Probe

  • 1.  SMTP mail server issue in Emailgtw Probe

    Posted Jan 17, 2018 11:14 PM

    Dear Team,

    We have configure the SMTP server in Emailgtw probe to get email alerts but we are not able to get nay alerts mals.

     

    As we cheked the connection of SMTP is successful there in test section but we have not provided the credential of SMTP, this is because that my mail server has told that you dont require any auth. to send any email. You can ignore this, it should work without auth. But it is not working, as in same server i checked with cmd prompt, from there i am able to send mail from smtp by telneting.

     

     

    Also want to know, how can we use SMTP server without auth. in emailgtw probe

    mentioning the error that getting in emaillogs...

    Looks like some authorisation issue as from SMTP side the connection is not identified as secure.

    Can you try to test mail flow through command line from the server where the emailgtw probe is installed.
    Below link gives some insight on utilising commandline for mail flow test.
    https://support.managed.com/kb/a2313/how-to-send-email-locally-using-command-prompt.aspx

    Also confirm if you're using TLS at SMTP end and accordingly set it up in probe.

    Hi Sinab,

     

    Thanks for your reply but as i mentioned earlier we are able to send mail by telnet from command prompt.

     

    Please suggest anything else that can be helpful to rectify this problem...

    **** Yusuf, please open a support case for this question so we can collect debug log information and investigate to determine the root cause.

    Hi,

    I am having the same issue in our environment. I hope to get help and hopefully someone can share additional thoughts. I did the suggested telnet checking and I got the same issue as Yusuf is getting.

    Kindly advice. Thanks.

    what is the type and version of the smtp server you are using?

    Have you checked with your SMTP server admin on the reason for the auth failure.

    If we assume the username and password are correct and we are still seeing an auth failure the SMTP admin would need to answers this.

    It could be an IP restriction or something else.

     

    There is not much more information from the emailgtw probe side we can provide why the SMTP server does not accept the user name and password being sent.

     

    it was not stated if you tested with Telnet from the same machine as the probe using the same username and password and if this worked or not.

     

    If it did not the probe can not work either.

    what is the type and version of the smtp server you are using?  - Exchange 2010 sp3 ru19
    Have you checked with your SMTP server admin on the reason for the auth failure. - this is now being checked.

    Thanks, Gene, for the guidance.

    If you set the emailgtw loglevel to 5 and logsize to 10000 and cold start it (Deactivate-Activate) you should be able to see an SMTP error number. The machine (primary hub) where the emailgtw is running should be allowed and able to connect to the upstream mail gateway to send mail. Contact your mail/exchange admin to make sure that the server is allowed to send mail (internally/externally). Your mail admin may also be able to tell you if the mail gateway logs show any related errors.

    Stephen, thanks for the input. Below is what I got in the log after I started the emailgtw probe. I then run the test that is also in the log below. Can you please guide me on the SMTP error number?

    Are you sure you need to enter credentials/need to authenticate?

     

    Have you tested the connection without the username and password, and without TLS?

    Wow! I never thought it would work without the credentials. I removed them and tested successfully. Below is the log of the testing and GUI is showing green. Thanks, Stephen!!!

    My pleasure, glad to help! Yes, for the most part your emailgtw log looked ok, except for the auth.
