is rumored to have said:

Ok I am popping email from an external server (aol etc)

Using an unnamed tool with unspecified config...

i get the proper email from address in the header's and resend all works ok if i am popping local email

ie t...@scom.ca --> p...@scom.ca postfix lets it go as is

when i get an external email with x...@aol.com (for example)

postfix replaces the from address in the header with scom...@mail18.scom.ca

Are you sure it is Postfix? Why?

Show the relevant config and log lines, as is urged in the documentarioin when asking questiuons here. No one here is telepathic or clairvoyant.

I understand why but it messes up the customer when replying ???

If you really understood why, you'd fix it yourself.

Simply put how do i preserve the headers when popping from a foreign server

Fix your Postfix config, probably.

Unfortunately, NO ONE here knows how to help you because you didn't share your config.

if there is a way to do this locally great as i would rather leave the security feature in tact

What "security feature" would that be? One that rewrites your mail incorrectly? Seems like a bug to me...


i am running this through a python email program and sending via the sendmail library

i am running multiple servers so i can program an inside one to bypass this if nessesary

otherwise how do i just turn off the 'from' address getting mangled?

Remove or repair whatever Postfix config YOU have which is doing that. There are multiple possibilities.

We can only guess which rewriting mechanism you have configured your server to use to rewrite From headers in your email with your domain.
