Hi people. We're stuck on an strange situation when sending mails to a particular domain:
- when we send something to "[EMAIL PROTECTED]" their server responds with "550 not local host mail.domainB.com, not a gateway". - this "domainB" is the domain of the company that's hosting domainA. - I've sniffed some traffic in our server (qmail-ldap 20041201) and it turns out that it's actually sending the mail with "rcpt to: [EMAIL PROTECTED]" instead of subdomain.domainA.com! - by inspecting their DNS records, I get this: host -t MX subdomain.domainA.com subdomain.domainA.com is an alias for mail.domainB.com. dig MX subdomain.domainA.com ;; QUESTION SECTION: ;subdomain.domainA.com. IN MX ;; ANSWER SECTION: subdomain.domainA.com. 75256 IN CNAME mail.domainB.com. It seems that they don't really have an MX record for subdomain.domainA.com! They just have a CNAME pointing to their _real_ server. And anyway, mail.domainB.com accepts mails for @domainB.com but not @mail.domainB.com, hence the error we're getting. Is this DNS configuration right? I mean, can they just CNAME a domain to their virtual domains' mail server and expect it to work, without an MX nor an A record? Funny thing is, there're no problems when sending mails from other domains (gmail, yahoo, hotmail, a local University account, whatever) to this [EMAIL PROTECTED] So, are their DNS records wrongly setup, or is our qmail-ldap server acting funny? Thanks in advance. -- Vicente Aguilar <[EMAIL PROTECTED]> Departamento de Sistemas Tlf.: 965 98 71 92 Recursos en la Red, S.L.U. http://www.renr.es
