Hi again,
I realized than same error is raised when database is in utf8 if email
contains utf8mb4 characters.
Which is the convenient database collation for postfix? We can force
postfix to accept only utf8 characters?.

in latin1, not only fails query, all sesion/connection is corrupted and
produces a lot of "temporary lookup table" errors until sesion is
recreated (about 1 minute later).

Hi!,
There are any way to implement equivalent to "warn_id_reject" for milters?
I'm deploying centralized spam milter on inet:X: and I would

Thanks!

sasl, I'm just implementing several approach, and I configure 2 diferent

em...@domain.tld alias,em...@domain.tld
Another one with authorized domains:
regexp:authdomains.map
/.*@authorixed\.
Totally true. Sorry and thanks!

Thanks for the proposals, the main problem is accounts names and domains
could be totally different. I'm reconsidering this approach to add only
selected accounts to able to cross domains, simplifing automation and
increasing security. Although it requires more config for client.
Thanks a lot.
