Any ideas how to deliver mails again? Thank you!
So you can not send out mails, or you can not receive? or both? Is this only with one external mailserver or all?
Postfix rejected because it couldn't verify the sender via lmtp; dovecot-lmtp replied that it is an invalid domain in the sender address. Not sure what's going on the, but restart mail services if you have not. Then I would re-enter your email address in your mail client, maybe it got some non-printable character in there? Or try sending with another client, eg. roundcube.
@Th0m sending is possible, to any domain. recieving is not possibie, no domain on this server can recieve mails. @Jesse Norell no mailbox is recivieving mails. every mail to an existing or nonexisting is noqueued. In the meantime I restarted the mailservice (postfix) several times and the machine once.

You can ignore the symlink warmings. What are your new symptoms and log messages from when it happens?

Try doing a forced update of ISPConfig and reconfigure services: Code: ispconfig_update.sh --force If you still experience issues, search on the forum/online for the MySQL errors you saw. You can do a send/receive test with https://ismyemailworking.com/
I did the reconfiguration, but with no effect. mail.err Code: Feb 7 22:08:37 monarch dovecot: auth-worker(18580): Error: mysql(localhost): Connect failed to database (dbispconfig): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) - waiting for 5 seconds before retry https://ismyemailworking.com/ is not working today - "Our apologies but we are experiencing technical difficulties at the moment. Please try again later." hm, any further ideas? TIA
