I have three CentOS machines on the network in an anycast config all
doing DNS, SMTP and NTP. I'm old school, so it's BIND and Sendmail. All
three have the same local user account/password that the MikroTik's use
for SMTP auth. It's not real complicated.

that's probably what ill end up doing, I just hate exposing an open

What we do is run a server with postfix as a open relay, except
that it is locked down to only accept mail from a whitelist of
ip's, which we enter from a web based interface that we wrote so
any of the techs can enter it.

I don't think you can provide a local smtp server on a Mikrotik.
I /think /you could use a dst-nat rule to point them at another
mail server.
ip firewall nat add chain=dstnat protocol=tcp dst-port=25
action=dst-nat to-addresses=[your mail server of choice]
to-ports=252525

----------------------
So theres no mail component like sendmail
Spf is a dns entry, i use rhem for relays alot
Open relays are great with ACLs, removes the authentiaction
failure without notification point of failure
