I use miab and love it. I need to send email using a different sender address.
The problem with this solution is while I can email using From firstname.lastname@example.org, if I want to email others that are on bbb.com (which I dont host) like email@example.com it won’t work because miab thinks bbb.com is on my server
any ideas how to get around this ? so i can send as firstname.lastname@example.org but also email other address at @bbb.com which is on another server
