postfix?

a) Set a correct sender address in your MUA.
b) Set myorigin to a hostname that is acceptable for other servers.
c) Use canonical_maps.

I=B4m not quite sure of what i need, i have an unusual setup of postfix=
+=20
mysql + maildrop + courier-imap + cyrus sasl, the major problem is that s=
ome=20
users have full email as login and some dont.
There is nothing wrong with postfix but cyrus sasl underts the @ part as=20
realm and when users with out realm try to send mail it must first auth =
to=20
postfix but cyrus append @localhost.localdomain to the users name.

To bypass that i have set smtpd.conf:
SELECT crypt FROM users WHERE id =3D=20
REPLACE('%u@%r','@localhost.localdomain','')

So users with realm @localhost.localdomain get the realm "" and users wit=
h=20
full email as logins stay as it is and that work for now. But the other=20
problem is some mail it geting bloked becouse my envelope sender says=20
localhost.localdomain.

Do you know where i can get some info about it? Googling results show onl=

how to block spam based on envelope sender.

Look at $myorigin. Also check if the users specify the correct envelope on
their own.
