Mail server madness (with regards to domain names)

2001-01-17 Thread Peter Schuller

Hello,

lately, outside (non-local) SMTP servers have begun to go crazy. For
example, I have a standard entry in my qmail virtualdomains file for all
mail to [EMAIL PROTECTED] - it goes to the user scode.

But if I attempt to send an E-Mail from an outside source (a few have been
tried) to, say, [EMAIL PROTECTED], the SMTP server making the final
delivery suddently goes mad and does an RCTP [EMAIL PROTECTED]!

What might cause this? I even changed "scode" back from being a CNAME to
being an A record in the DNS configuration, in case that was the cause.

Note, my main address "[EMAIL PROTECTED]" works fine.
mail.infidyne.com is the MX for the domain.

Any suggestions would be appreciated. The strange part is that we didn't have
this problem earlier.

Thank you,

Try creating an MX for scode.infidyne.com.

CNAMEs are a bad thing for email. Check the discussion in THOUGHTS.

Change your DNS so that scode is an A rather than a CNAME and the
remote MTAs won't bother doing the re-writing.

...and don't test it again until the CNAME is gone (it's time to live
expired) as tests from remote machines will find the CNAMES for another
while after you update your DNS.
