=== My wiki won't send email ===
If you're not outsourcing everything through a third party, you'll want to implement [[SPF]] and [[DKIM]] and [[DMARC]]. Even if you're using a third-party like GAFYD, if you've got a [[CiviCRM]] instance managing all your constituent mailing, then you're going to need to setup these anti-spam measures.
=== How do I'm on a server and I need to use the 'mail' command ? ===You're on a linux server and you see "You've got mail". So, you type 'mail' and immediately have no idea how to process the messages. See this excellent tutorial/write-up of the basic '''mail''' command: http://www.johnkerl.org/doc/mail-how-to.html The <code>mail</code> command works like the editor '''<code>ed</code>''' which is to say not very well known today. (See <code>man mail</code> -- The manual page was written in 1993.) The man page refers to [https://docs.freebsd.org/44doc/usd/07.mail/paper.pdf The Mail Reference Manual] originally written by Kurt Shoens
