guys,
this still isnt resolved…even after webmin update yestaerday 6.09-3, i thought that perhaps the error the original webmin update caused in dovecot was fixed. however, i wake up this morning and again i find dovecot has shut down enterring a failed state.
this is plain crazy what on earth is going on with these updates?
have a look at the dashboard system monitors…one says dovecot is running the other says it isnt!
We need to see the maillog entries related to the failure. I don’t see this behavior on our servers, so I don’t know what’s happening or why.
ok i will try to get them now.
what is really strange is that i managed to get dovecot restarted, however it is not delivering for one particular domain (the same one that went haywire after the webmin update 6.09-2)
Here is the last 100 lines of the mail error log…(im sorry its so long but i thought that will give best chance of narrowing down what is wrong with the errant domain…

This is probably the root cause. Check your dovecot.conf for the ssl_cert path (and possibly ssl_key, etc.) to see if the files exist where Dovecot thinks they do, and make sure they’re actually in PEM format.
I’m getting vague notions from various problem reports that maybe there’s a situation where some certs that Virtualmin is copying into place aren’t a valid format for Dovecot (and it may be Dovecot version dependent). But, I’m still guessing pretty wildly and I don’t really have enough data…I probably need to see your Dovecot config file (sanitized if you don’t want to show domain names or paths). And, I need you to tell me whether there are actual PEM files in the places Dovecot is looking for them.
Hi Joe, i am more than happy to give you access to my Virtualmin Pro system directly.
I am now doing the following in Webmin for you…
