I’m looking into upgrading my email setup. I use mutt, and need two features:
- Local queueing of emails, so that I can write emails when offline, queue them, and send them later when I’m online.
- Routing of emails through several remote SMTP servers, ideally depending on the From header, so that emails pass SPF/DKIM checks.
I currently use nullmailer, which does queueing just fine, but cannot apparently handle several remote SMTP servers.
There’s also msmtp, which can handle several “accounts” (remote SMTPs). But apparently not when using queueing using msmtpq.
What are you using yourself?
