Hi all,
I
have a problem with postfix, I have my postfix set up on the domain "a.com" and
am getting in the queue of emails incoming email for example
the domain from "u...@b.com" to "u...@c.com", the domain "b.com" and "c.com"
with and are not part of domains that postfix has served as an area. I
was reading the documentation postfix.org and says that by default
Postfix has to meet only the domain specified in the variable $mydomain, then
why is he accepting these emails? detail:
e-mail enters the queue, Postfix uses SASL, so it can not send emails,
but would not want to enter the queue and possible? I thank you.
