I upgraded to Dovecot 2.3.0.1 as advised, but it still seems broken. In
the Postfix log I now see:

I can see in my MySQL Log that Dovecot queried at the same time with %n
= "" (empty) and %d = "@mydomain.tld". So now the
"@" is dropped entirely.
What does the "Fatal: Invalid -f parameter: Missing domain" tell us?
Do
I need to change the way Postfix calls Dovecot? Add more quotes? :D
Kind regards,
Philipp
