SquirrelMail

**Removed Sendmail

So i can receive an email from anywho@anywhere.com and i can now send to anywho@anywhere.com the only problem i have is that when i send to anywho@anywhere.com it comes though as me@gmail.com

I would like it to come through as me@mydomain.com

It looks like my sending domain has changed. Did i do something wrong

I could post my logs but they do not give any errors so im not sure how much that would help.

Anything else i can post let me know

Answer 1

You're using a relayhost.
It should go out as you@gmail.com because gmail swaps the sender to reflect your gmail account.

You can send email as you@domain.com only if you have a STATIC ip. Dynamic IP addresses are blacklisted by most email providers.

If you have a static IP, just remove: relayhost, *smtp_sasl_password_maps* and generally sasl unless you know what you're doing.
