Re: DNS lookup for SMTP

It really shouldn't be doing anything for a mail router. As I said before,
there shouldn't be MX records, in most cases, for a mail router host name,
especially an internal exchange server, so it's really a moot point.

If there are MX records set up for your mail router's host name, I would
ask why that's the case.

So since I have a mail router defined, the mail router host should be
looked up using the A record instead of the MX?

Thanks

It sounds like IBMi is operating correctly and MX takes priority over A

for SMTP.

As Brad mentioned, if a mail router (or smart host) is used, then the
actual MX records should be ignored and all mail should be sent to the
router / smart host.
