SMTP service crashing on certificate related exceptions, versión

Post by rgomez » Wed Aug 25, 2021 6:21 am

Hello,

I've been using MailEnable for a long time (10 or more years) and this is the first time I remember having an issue like this. In the past week I have had to start manually the SMTP service twice because it crashed, apparently (according to the SMTP debug logs) because of some issue handling certificates.

I have 10.35 version, installed on the last month (I don't remember exactly when, but it is indeed recently).

Here are the related messages in the debug log for this two crashes:

----- Crash 1 -----

Code: Select all

This were the last lines on the debug logs on both occasions, so I assume those caused the problem/crash.

Any idea? Shall I return to the 10.34 version?

Thanks!

Hi,

The 10.36 beta kit on our beta page contains the fix for the SMTP crash.

I have the exact same issue with 10.37.

Do you have any suggestions?
