Re: Manipulate RPCT from an specified SENDER.

Noel,

Thanks in advance. A few seconds after sending the prior mail, i found that info =).

So what i did was:

in main.cf: smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/access

in /etc/postfix/access:

source@ REDIRECT destination

Then postmap /etc/postfix/access to generate the .db.

Restart postfix and that was all I needed =)

THANKS AGAIN !

Regards,

Hi all,

This is my first message here so please tell me if i'm doing something wrong or perhaps what I'm asking has been already resolved.

I have two servers running postfix. *A* just sends mails while *B* acts as a relay host for it.

*A --> B --> INTERNET*

What i'm looking for is to rewrite the DESTINATION of e-mails send by a given SOURCE. Lets say:

If server A sends:

FROM: example@source.com
*TO: example@destination.com*

Then server B or A should see that if it comes from example@source.com, no matter which recipients does it have, it should *rewrite the TO statement to something@destination.com*:

FROM: example@source.com
*TO: something@destination.com

*The thing is that the TO is constantly changing so I have to filter mails by FROM and not TO.


Any clues ?


The REDIRECT action from an access table can direct mail from a specified sender address to a fixed recipient address.  This may or may not do what you need.  Note the REDIRECT action affects all recipients of a multi-recipient mail.

Maybe it would help if you explain the actual problem you are trying to solve.
