Need help to block/allow incoming connections based on IP
Dear all, After hours of reading websites and this mailing list, and after many unsuccessful tries, I would be happy if someone could help me. I want to allow some incoming networks to be allowed to connect to our servers and all the rest to be blocked. This is the solution that I ended with (but it doesn'... 22 Jul 2010 08:07
Feature request: postsuper release but don't delete (cloning?)
I can put a mail on HOLD and release it later with the postsuper command. That's great for debugging purposes, but only if I need to send the message just once. Would it be possible to expand the postsuper command with an optional command line parameter that releases the message, but does not delete it from the h... 23 Jul 2010 09:11
Rewrite MAIL FROM protocol message
Hi, I've got a local mail server that is responsible for delivering all my mail to the recipients. It does this by forwarding it to the strato mailserver using smtp authentication. As I do have accounts with different providers, my mails do have different sender domains. That's why the strato mailserver refuses ... 22 Jul 2010 04:52

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 ... 21 Jul 2010 10:14
Is such an SSL attack possible against Postfix? sorry, it's in german. I'll translate some bits: Sombody went to Torrent trackers and announced as Torrent client (for a really popular download I guess). Thus, got flooded with torrent-client traffic on the SSL port. Port 25 outgoing will b... 21 Jul 2010 23:29
What is the proper way to deal with non-existing e-mail addresses?
When somebody emails to a non-existing e-mail address postfix bounces these by default with a "Recipient address rejected: User unknown in local recipient" error. I wonder what the appropriate behavior is. To discard emails for unknow, users, forward them to another address or bounce them? What about backscatter? D... 21 Jul 2010 03:46
