I really doubt if this has anything to do with the 3rd interface,
that's just a coincidence.

from?  I can't send anything to you.

Same result from two different ISP's.  That should work fine, not kick
back a syntax error/spam block.  Of course that has nothing to do with

That's inbound, not outbound.  Can you 'telnet mail.chrisbuechler.com
25' from your network?  If not, try to 'telnet mail.yourisp.com 25'
(where mail.yourisp.com is really your ISP's server) and see if that
works.  If the former doesn't work and the latter does, your ISP is
dropping 25 outbound.  If both of them work, you have some sort of
mail server problem.  If neither of them work, you might have a
firewall issue.

The work around, if you can't get your ISP to permit SMTP outbound
from you, is to use their mail server as a smart host.  That really
doesn't defeat the purpose of having a mail server, though it's
certainly inconvenient if you want to check outbound queues.
