SMTP service Failing - Timeout

0 votes

With the latest version, sometimes the emails never get sent and no error message exists in the log files. When I notice this happen, I try sending a test meail form the Service Properties page and I get a screen titled: Test Settings Failed and the message is: The operation has timed out.

If I restart the server(restarting the service does not address the issue), mail starts working again but it never sends any of the messages that failed.

This is a real reliability problem that I need to get fixed ASAP. Please advise. Thanks!

Version 2012.1 Version 3.3.8318.0

Hello Michael,

Please execute the following PowerShell script:

    $smtpServer = "smtp.company.com" # TODO: modify me
    $emailFrom = "emailFrom@company.com" # TODO: modify me
    $emailTo = "emailTo@company.com" # TODO: modify me

    $smtpClient = New-Object Net.Mail.SmtpClient($smtpServer)
    $smtpClient.UseDefaultCredentials = $TRUE
    $smtpClient.Send($emailFrom, $emailTo, "Subject", "Test")

Does it send email successfully?

It did not work
SendEmail: 1 operation executed
Run PowerShell script 'smtp email' for the user
Exception calling "Send" with "4" argument(s): "Failure sending mail."

I also tried sending a test message through the properties tab and it failed again with the same Timeout error.

Please note I have also upgraded to the latest version from the website Friday, so that didn't fix it either...

Michael,

Try executing the script via the Windows PowerShell Console, not via Adaxes.

That worked fine through powershell. Trying the Test Settings button still failed. Thanks!

Michael,

We managed to find the cause of the problem. Email messages are not sent because .NET System.Net.Mail.SmtpClient class doesn't issue QUIT command to SMTP transaction. That's a Microsoft's bug, but we'll try to workaround it. On Thursday we'll release a minor update for Adaxes that contain a fix for the issue.

Hello Michael,

Today we released a minor update for Adaxes 2012.1 that contains a workaround for your issue. Find the latest build here.
Upgrade instructions.

After you update to this build, find the Softerra.Adaxes.Service.exe.config file located in the directory where your Adaxes service is installed. Find the following line in this file:

<mailWorkarounds maxIdleTime="-1"/>

Change -1 to 2.

Please, reply if this helped.

Completed this upgrade to 3.3.8530.0 mail still stops from time to time and when I test I get the same error message previously communicated. What next?

Hello Michael,

Did you try restarting your Adaxes service?
Which e-mail server do you use?

Exchange 2010, restarting the entire server is required to get it working again. Thanks!

Hello Michael,

Can you send us the log of the SMTP protocol? This article by Microsoft describes how to enable SMTP logging: Configure SMTP Protocol Logging
After you enable logging, the log file will be availble at the following location: ...Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs\ProtocolLog\SmtpReceive.

Hello Michael,

Please have a look at the Adaxes Event Log. See this help article on how to view the log: Service Event Log

Do you see any of the following errors appear in the log?

System.Net.Mail.SmtpException: The operation has timed out.
System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: The operation has timed out.

Yes here are the details

I've noticed that this occurs when it is sending a large amount of emails and usually the first error precedes the beginning of the failure errors. Let me know what or how you want to recieve it and I'll export and send you the entire log. Thanks!

Latest upgrade and service configuration set as emailworkaround = 2 has not thrown this error in 4 days. I think we're good. Thanks!
