I have a request I am trying to determine the feasability of. Assume we have the following email addresses sending email:
When these accounts send email, we want to rewrite their address as
Basically dropping the .abc part of the username.
I am familiar with masquerading, but is it possible to do this using something like a wildcard? There could be up to thousands of users matching this pattern, and I don't want a masquerade entry for each.
Can you do something like:
*.firstname.lastname@example.org ---> *@mycompany.com in the masquerade?
Any other way to rewrite these? We need to rewrite the from, cc, reply to, etc so I am thinking Masquerading is the right answer.
Hello Tony, I had a look into the ESAs availability and i was unable to get this type of setup to work to have a wildcard value.
I do notice, Reply-to, From headers are within the header side of the email. The "CC" (at the envelope level are stored as envelope recipients) so we cannot alter it with a wildcard value, however in the "cc" headers which you see on your MUA we might be able to edit with a message filter to look for these headers, find the string .email@example.com and replace it with @mydomain.com
Essentially when an email comes in with the Header values of
From: Mathew <firstname.lastname@example.org> To: Matt <email@example.com> CC: anotheruser <firstname.lastname@example.org> Reply-To: <email@example.com> Subject: This is a test sample
This is a test.
We can re-write these headers so when they appear on the MUA, we can replace anything .firstname.lastname@example.org to mydomain.com effectively displaying:
From: Mathew <email@example.com> To: Matt <firstname.lastname@example.org> CC: anotheruser <email@example.com> Reply-To: <firstname.lastname@example.org> Subject: This is a test sample
This is a test.
In your outlook for example. I believe this is as far as (i can think of anyway) we can go on the ESA side.
