Just had a weird issue. Clients told me mail was bouncing, so I checked the mail log and noticed mail would still come in, but not from the clients. They got bounce message from Sophos stating nothing but "Internal Server Failure". After a little bit of searching, I found that the appliance reported that the SMTPD service was dead, in the dashboard. (Would be nice if this would be made more noticable).
Now, I found that by going to services, there is no SMTPD service listed. So, there is no way to restart it. Leaving only an appliance reboot. After this reboot, the service was still dead. Took me a while to figure out the log file for this service is the awarrensmtpd.log file. In there, it logged the following error :
ERROR Aug 11 17:39:09 [4144936704]: reading private key '/conf/certificate/private/.key' failed for 'error:0906A068[[:P]]EM routines[[:P]]EM_do_header:bad password read'
Well, this is strange. I haven't touched the certificate configuration.... I figured I'd just re-upload the certificate and see if that would work. No go.. Upload successful, but upon reboot the service would still be dead with the same error.
Eventually I changed the format of the certificate and uploaded a .pfx file. After a reboot, everything was up and running again.
Anybody else experience something like this?
