Hi, I'm new in this mailing list,
I have setup a test server (localhost) with POSTFIX (of
course!)+DOVECOT+SASL+UBUNTU 8.10 with Virtual Mailboxes.
I'm testing the SMTP authorization system and it seems to work fine:

Hello!
A quick question (I think).
According to the Postfix Manual, "reject_unlisted_recipient":

and "smtpd_reject_unlisted_sender":

I use "reject_unlisted_sender" in that situation (from hotmail to a local

If I understand correctly the Postfix manual,
"reject_sender_login_mismatch"
is equivalent of adding these 2 rules instead:
"reject_unauthenticated_sender_login_mismatch"
"reject_authenticated_sender_login_mismatch"
right?
If I use SASL authentication, which one is recommended
"i...@domain.tld"
2) add "Bcc: i...@domain.tld" to all outcomming email that have "[INFO]" in
the subject and not "i...@domain.tld" in "To", "CC" or "Bcc" headers
More in general I want to know, if it is possible, how I can write some
filters to change the email header and body.
Thank you for the help.
Alberto

Hello, I need some advice with a problem (I believe is an easy question but
I couldn't find an answer):
My server logs is "normally" reporting twice almost every time someone is
sending an email:

I have to say that I haven't confirm the email "duplication" problem. I have
no way to test it from here and I have no information about the email client
settings. Its just a problem reported from one user from hundreds. However I
would like to rule out first any server related misconfiguration.
I have found this link:
http://www.mail-archive.com/amavis-u...@lists.sourceforge.net/msg04286.html
in which almost the same problem as mine is described. However my setup is
different. This is what I have:
OS: Ubuntu 8.04 (Hardy) x32
Postfix: 2.5.1-2ubuntu1.2
Amavis: 2.5.3-1ubuntu3
ClamAV: 0.96.3

Yes Matt, I agree with you.
However, for some reason a customer is complaining that some people are
receiving several copies (in one case up to 15 copies) with exactly the same
content, when he/she sent just one mail.
I thought at the beginning it may be a problem with his mail client but

Thank you in advance, and sorry to take your time.

Does anyone know why is this happening? Is this important? How can it be

There is a customer that is sending mails from excel using a banned client
in the server "header_checks" restrictions (client can not be changed due
to technical restrictions).
I allowed the customer in sender_access, however postfix is still blocking
it.
How can I set "sender_access" to be before

I'm running a Zentyal (based in Ubuntu) server, which comes with an already
configured postfix server (based in few settings) using LDAP as user's
database.
We are using that server to send messages to mailing lists. Most of the
mailing lists looks like:

I updated my server from Ubuntu Server Hardy (8.04) to Precise (12.04) and
I found out some changes in the setup (specially dovecot and amavis, which
I think I solved).
No errors in mail.log / dovecot.log.
POP and SMTP seems to be working fine. I sent an email to another account
in the same server

One of my customers is receiving a huge amount of "very specific" spam not
blocked by my regular postfix's spam control rules:
The spam is coming from several ip addresses.
All mails have this client:
X-Mail-Agent: BSMTP DLL Feb 11 2001 by Tatsuo Baba
Which would be the best way to block it?
I added "header_checks" (regexp) to main.cf. I will test it.
Thank you.
