3/9 Assuming no .mailrc file where does the "mail" command pull the
domain for the outgoing email address?
\_ The system-wide mailrc if it exists (often /usr/lib/mail.rc or
such, see the man page) - otherwise it gives none and lets
sendmail add it.
\_ Not everyone runs sendmail.
\_ Yes, but everyone is going to have some sort of mail
delivery agent. Nice try.
\_ But mail/mailx are usually hardcoded to run sendmail,
so people who run something else have to replace the
sendmail binary with something to call their preffered
MTA.
\_ soon, every MUA worth using will support MSA
\_ What's the advantage of MSA over SMTP?
\_ What's MSA?
\_ is it an addition to, not a replacement for SMTP
think MTA agnostic way for MUA's to submit messages
to any SMTP MTA. write to socket (AF_UNIX or INET)
You can also have more flexibile relay rules. Lock
down port 25, have port 587 (MSA) more open for
things like remote pop/imap users. |
