While I am not sure, there have been numerous changes/fixes to the DNS code from 1.21 to 1.27. I would definitely recommend upgrading to 1.27, besides the DNS issue. - Davide ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail

[xmail] DNS Issues
Hi, I'm using an old Xmail 1.21 on Windows server 2003, which has been rock solid for years. Recently I've started to see occasional DNS issues where xmail is attempting to send to the A record IP rather than using the MX. Looking in the Xmail MX cache folder, it has the correct MX servers for the domain yet still sends to A record. One particular domain that causes this issue regularly is kumon.co.uk. It has 2 mx records (correct in the xmail MX cache) and an A record that points to a different IP. Xmail connects to the A record, which appears to be running a mail server for some other domain! Also, if i turn on the 'check mailer domain' occasionally I get incoming mail rejected as 'your domain has not MX records', even though I can do a manual mx lookup ok. I'm running my own Bind 8 DNS server on the same machine (for several years also), I'm thinking there must be some connection or timeout problems somewhere. Do you think updating to the latest XMail would improve this? Thanks Dave ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
