nobody@hostname in php mail() Return-Path

[moronhead]

Undeliverable mail sent by a user with PHP mail() gets returned to nobody@hostname instead of the user. That's because the Return-Path always seems to be set to nobody@hostname no matter what headers are used in mail() to try to redirect the Return-Path. We tried Errors-To, Return-Path, &-f$sender& so far with no success.

Has anyone found a way to change the Return-Path?

Very useful. Many thanks.

Setting this in exim.conf:

untrusted_set_sender = true

enabled &-f$sender& in PHP mail()

I'm not yet sure if there are any security implications with this but it worked.

Best regards,

so do the headers look like you want them to now? I have been having this problem for a while. Can the script specify what the header looks like now? .. I know before certian things never worked.

The -f parameter in PHP mail() is working correctly with the above fix. It is redirecting the Return-Path to the address set in that parameter. Before that fix the Return-Path was always being set to nobody@hostname so any undeliverable mail used to end up returned to us instead of the user.
