(slightly off topic)

In my experience, postfix is very nice about trying multiple MX records.
It should try every MX record twice. I normally wouldn't have posted,
but yesterday I remember seeing how many connections it tried to do
every time it delivered mail through fedex:

tstromberg@calamari (~)% host -t mx fedex.com
fedex.com mail is handled (pri=100) by mapper.mail.fedex.com
fedex.com mail is handled (pri=200) by smtp.zmd.fedex.com
fedex.com mail is handled (pri=300) by smtp.dmz.fedex.com

tstromberg@calamari (~)% gzcat /var/log/maillog.0.gz|grep 76000
Feb  7 17:19:25 calamari postfix/smtp[76000]: connect to
mapper.mail.fedex.com[199.81.10.25]: Connection refused (port 25)

This is with the postfix 20010204 snapshot. I can't guarantee any other
versions.
