How do I set Return-Path for sendmail?

[ajaydsouza]

Hi,

Currently any mails that are being sent out by PHP have the Return-Path set to nobody

As a result any bounce notes are landing up at nobody which forwards to my server email address.

How do I ensure that the bounced emails actually land up to the from or some other email?

use the sendmail with -f or use something like:

mail("[email protected]", "subject", "message", "From: [email protected]", "[email protected]");

the last (5th) parameter "[email protected]" is the return address

I think ajaydsouza wants do do it server wide not edit each script one at a time
there was a how too somwhere on the forums but I could not find it

open exim editor avanced editor and add this code to the REWRITE CONFIGURATION box
(6th box down)

[email protected];/etc/localdomains "${if !eq {$header_From:}{}{$header_sender:$header_From:}fail}" Fs

I think thats all you need to do

@ujr, Thanks. I was aware of the fifth parameter, but didn't want to use it because I can't ask everybody with me to use the same

@dalem, can you explain to me how exactly the code you gave me works?

 

[dalem]

yes when a php script sends mail as nobody exim rewrites the mail header thats it

 

[ujr]

what dalem suggested works server wide. That's what you wanted.

As long as there is a FROM address, it will re-write it properly.

That is good, it replaces the Return-Path to the same as From correct?

In case the script doesn't set a From?

Actually, what I wanted was a line by line explanation of the code

Have added to my mail server, can give it a test.

no, the line {$header_From:}{}{$header_sender:$header_From:}

will only match the FROM.

If you wanted to match the reply to you'd have to expand on it, and first check if the from is set, then test to see if a reply-to header was set.

I realized that this is needed. I got one such email from PHP where the from wasn't set but the reply-to was.

Do you know the code for checking for Reply-To first and then From ??

>>Do you know the code for checking for Reply-To first and then From

You'd want to check the from first, and use that as your sender...not the other way around.

hmm.... am going to have to learn Exim Rewrite rules

You'll find that what dalem posted above will work 99% of the time.
