First off: Courier-mta is the BEST! Question: Does courier iterate through all available MX records even if the first few are broken and possibly violate RFC1035?
I have been getting a complaint from someone trying to send an email to me. She gets an error from her mailserver thus: -------------------------------------------------------------- >>> Mail Delivery Subsystem < [EMAIL PROTECTED] > 1/6/2004 3:43:24 PM The original message was received at Tue, 6 Jan 2004 15:43:14 -0600 (CST) from 12-23-34-45.otherguysisp.com [12.23.34.45] (may be forged) ----- The following addresses had permanent fatal errors ----- < [EMAIL PROTECTED] > (reason: 517-MX records for brokendomain.com violate section 3.3.9 of RFC 1035.) ----- Transcript of session follows ----- .... while talking to mail.! mydomain.net.: MAIL From:< [EMAIL PROTECTED] > SIZE=1911517-MX records for brokendomain.com violate section 3.3.9 of RFC 1035. <<< 517 Invalid domain, see <URL: ftp://ftp.isi.edu/in-notes/rfc1035.txt > 554 5.0.0 Service unavailable --------------------------------------------------------------- It was explained to me that the other guy's ISP (otherguysisp.com) has the broken domain's entries purposely broken for the first few MX records (brokendomain.com). He says that his ISP wants to keep the first few MX records broken, and that the problem is with MY mailserver. I am running Courier-mta 0.43.2 and it was compiled on my redhat 8.0 box with the ldap auth module loaded and running. - Kirk P.S. this message may get posted twice as I had a different email address registered with mailman, and the first is presently being held under moderation. ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
