info about a Sendmail configuration
Hi to all! Sorry for my question about Sendmail and not Postfix.. but I'm in trouble! Here the question. I've a Red Hat server (hostA.domain1.dom) that should send mail trough an Exchange server (hostB.domain2.dom) to a destination address. The Exchange rejects the message because it does not recognize my domain (*.domain1.dom) What should I do in the sendmail.cf to permit the change of from field from *.domain1.dom to *.domain2.dom? p.s.: I cannot modify the Exchange configuration to add domain1.dom to known domains.. Thanks in advance! -- Stefano Villa
Info about another listening port on Postfix 2.3.3
Hi to all! I've a configuration file like this: smtp inet n - n - - smtpd -o content_filter=dfilt: and I have to *add* another listening port (TCP 37025). The line -o content_filter=dfilt: has the purpose to add a disclaimer to all my outgoing emails. If I add this line: 37025 inet n - n - - smtpd under the: -o content_filter=dfilt: the disclaimer will append to the mails trought the 37025 port too? Or I must copy the line -o content_filter=dfilt: under the line 37025 inet n - n - - smtpd too? Thanks to all! -- Stefano Villa

Postfix and Disclaimer
Hi to all! I've a postfix (2.3.3 version) server on RHEL (2.6.18- 164.11.1.0.1.el5 version). The postfix role is to relay messages to another Exchange server. I've the task to implement a disclaimer for all mail. What product can I use? Thanks! -- Stefano Villa
Re: info about a postfix problem
It works!!! Thanks! Stefano Use something like smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender_access permit_auth_destination reject If this server isn't used for incoming email, you can remove permit_auth_destination. Your use of a wildcard in relay_recipient_maps disables recipient validation. I can't stress how important it is that you use a real list of valid recipients. This will come back and bite you. -- Noel Jones -- Stefano Villa

I would like to permit relaying only from *...@domain.a/domain.b/domain.c/domain.d/domain.e/domain.f to any destination, and not any to any. How can I set up my postfix? Thanks!! -- Stefano Villa
