Re: Negation in header_checks doesn't work as expected?

If you can auto-generate them, you can auto-map them for Postfix. So far the postfix server I've setup can already accept the catch-all address and forward it the local account as intended, however I want to reject those that do not match the -keyword pattern, even existing for existing account that doesn't have the keyword in the name. I've tried using the regexp in header_checks, but as soon as I added the negation, it doesn't work as expected. For example: !/^To: (.*)-keyword@(.*)$/ REJECT = all mails get rejected That's probably because there are a *lot* headers in any given mail that don't match this pattern. ;) Try something like this: if /^To: @example\.com$/ !/^To: (.*)-keyword@(.*)$/ REJECT endif Regards Ansgar Wiechers -- Abstractions save us time working, but they don't save us time learning. --Joel Spolsky

H It looks like this could be solved more easily with a recipient delimiter and maybe some minor changes on the address generation side to deliver mail to keyword+...@example.com to mailbox keyw...@example.com automatically.
