Hello,
i used to create on-the-fly mail-addresses with "recipient_delimiter"
set to "."
Now, one of those mail-addresses is heavily receiving spam.
As this mail-address is of the form "user@...", cannot just remove
the user "user.sub" from my list of users.

Hello,
i would like to create the following setup for two postfix servers.

He does forward all external mail to Server B

Thank you, Noel!
I got that running - mostly :)
Server A (MX, SMTP: smtp.example.com) has:
relay_domains = $myhostname, localhost.$mydomain, localhost,

mynetworks = [ip.ad.dr.es], ...
Where /etc/postfix/mydomains lists all doma
I got caught by that already :-O
My server bounced two mails from the list (having relay_recipient_maps
set up wrongly) - and i have no idea if that was already an answer ...
So, if somebody answered to my last mail, please send it again.

Sorry for that!

For example:
