Hi postfixers,

Why this config

pickup fifo n - n 60 1 pickup
-o content_filter=smtp:[127.0.0.1]:25

postfix considers as loop but this one

pickup fifo n - n 60 1 pickup
-o content_filter=smtp:[127.0.0.1]:10027

doesn't?

Content filters are supposed to use a different TCP port.
Mail to the standard SMTP on the same MTA is a mail loop.
