Bug in SMTPDS?

[Zaxalon Webmaster]

I noticed that a certain piece of mail created a bounce loop on our IMS server.  It appears if a domain lists an non-fully qualified domain name in the MX record, that IMS uses the local domain for the lookup.   Take for instance rossbreeders.com   ---------------------------------------------- C:\>nslookup -type=mx rossbreeders.com Server:  dns1.stlsmo.sbcglobal.net Address:  151.164.14.201   Non-authoritative answer: rossbreeders.com        MX preference = 30, mail exchanger = mail   rossbreeders.com        nameserver = dbru.br.ns.els-gms.att.net rossbreeders.com        nameserver = dmtu.mt.ns.els-gms.att.net ----------------------------------------------   Note that the mail exchanger is not fully qualified.  It appears that a bounce message to this domain by IMS will create a mail loop if the machine name "mail" is also the name of your IMS mail server.  It appears IMS is resolving this non-fully qualfied domain name on the local domain.   I am not sure how to resolve this issue in IMS; if anyone has any ideas please let me know.  In the worst case perhaps a custom filter that performs a lookup could patch this issue, but I'm wondering if there is any configuration setting in EMWAC IMS or MMS that might prevent this sitaution.   -- Eric
