I have a multi-server set-up with one server processing mail for multiple domains using postfix/Courier/Maildrop. For one of the domains (eg. mydomain.com) I send out emails for clients (eg. [email protected]) using the "From:" format [email protected]. When one of these messages bounces, it goes to a catchall mailbox and I know where to forward it to from the local-part, and have been doing it manually. How can I auto-redirect these to the client? I assume I need to pipe the email to a php script, parse the local part and send it out? Can I get some pointers please on how to do this in ispconfig3 to get me started. Thanks, Ray
For others who might find this through a generic search, here's what I learned from SO and is working now: Mail Content Filter Server: **select your mail server** Filter: Header Filter Regexp. Pattern: /^To: (.*)_XYZ_(.*)@mydomain.com$/ DATA: ${1}@${2} ACTION: REDIRECT and check the Active box and Save. I'm sure there is a better Regex to match all possibilities for the To: header but this is working for me so far. I did not need to pipe it to a php/perl script or to procmailrc or use aliases. A couple of questions: does this Content Filter happen before or after rbl checks etc? I may need to find another solution if this is potentially opening a backdoor for relays.
