Postfix not working after adding SSL

My mail is receiving, not sending stuck in MailQueue here aare the files you need. I have been looking for DAYS no help on internet All comments taken out -- if it matters, my SSL is through letsencrypt. All my domains have their own but a default matching the 'master' domain was copied within virtualmin

Since I have absolutely no idea why it stopped working after 'forcing' SSL like the rest of my site(s) I may have broken something and not known it.

Also is there a pgp encryption, and how to use it.

Any help or insight as to where I puked it, would be greatly appreciated.

Some info's to read also forumrules say to post all software versions used and error log messages while in the blind.... for the support guys of virtualmin

And postfix info from postfix

So please read some and then post more info what didn't work with versions and errors or other messages. You can config in the admin GUI part or also there edit the config manualy.

You didn't say also with other mailpart you use ( dovecot? )

Do some telnet tests on your box to. And take care of ports trafic tcp, udp .. and firewalls

OK I have no idea on the version (whatever the last update in Virtualmin set it at -- all I know is I get mail but cannot SEND any mail and it started not working after SSL. I searched online for weeks and weeks and no help in ANY place, but every post asked for these two files.

But it seems there is no help here either -- maybe I'll just have to find how to swith over to Sendmail, but evenn THAT may Barf at me, I'd rather fix this, don't spew rules and sites at me, ofer help or don't.

I don't then. While above was help, but refusing to look a litle further for example how to find versions which virtualmin and OS and so on , i expect support can't help you either if not knowing more.

Good luck

You mentioned that the emails were stuck in the mail queue -- often when that happens, there is an error associated those messages.

What error do you see?

That is, try running this command:

mailq | tail -30

Can you share the output you see with that command?

Also, what if you try to send a new email, can you share what message(s) appear in the mail logs, which would be either /var/log/maillog or /var/log/mail.log?

atleast's picture

mainenotarynet Can you brief if you followed any instructions to config postfix and dovecot? If yes where. I can give you a link that I followed and it worked. After that I have had to tweak a lot. On this same forum there are many threads that discuss these issues. For now virtualmin handling of postfix is the best and extremely userfriendly but it still requires configuration. Please reply to last post of Eric and he can throw some light.

I will compare your configs with what i have on a functional setup and will revert
