I have seen IMail on a handful of occasions sending mail to an A record before an MX
record. Does anyone know if this is a known problem, and if it has been fixed?
As an example, there is a domain we have tried sending E-mail to several times today.
"domain.com" has 1 MX record, and 1 A record (which points to a different computer
than the MX record). The first attempts look like this, and went to the MX record, as
expected:
02:16 11:15 SMTP-(00000177) Trying [domain].com (0)
02:16 11:15 SMTP-(00000177) Connect [domain].com [111.22.33.44:25] (1)
02:16 11:15 SMTP-(00000177) 220 ...
But, a later attempt shows:
02:16 11:47 SMTP-(0000018F) Trying [domain].com (0)
02:16 11:47 SMTP-(0000018F) Connect [domain].com [111.22.33.44:25] (1)
This results in connecting to a mail server that doesn't accept E-mail for [domain]
(perhaps it is a web server, and only handles outgoing E-mail). The same thing has
happened with other IMail servers that have tried sending mail to our domain (our A
record points to the web server we use, which has an SMTP server, but doesn't accept
mail for our domain).
The serious problem is that IMail will report a bounce message if the A record doesn't
accept mail for the domain (which is very often the case), making it look like the
receiving domain is down.
Any ideas if this is a known problem and/or has been fixed?
