OK. So, I've got some clients that send mails out to affiliates of theirs via rather large distribution lists. When at least one, maybe more, of those addresses are bad, they get the "Sorry, can't find a valid MX for rcpt domain" bounce that, basically is bouncing the whole message, so even the valid recipients don't get the e-mail.
I've searched the archives, particularly: http://www.mail-archive.com/qmailtoaster-list%40qmailtoaster.com/msg27066.ht ml, and haven't really found anything that helps.Unless I'm doing something wrong. I've tried removing the references to CHKUSER_RCPT_MX in tcp.smtp, then issued qmailctl cdb, same issue. I tried setting CHKUSER_RCPT_MX="", and CHKUSER_RCPT-MX="0". Nothing. Tried setting CHKUSER_STARTING_VARIABLE="NONE".No change. I've read where the default CHKUSER config is to have these commented out, but it appears that this isn't the QMT default, per the linked thread above. How do I go about commenting these out in CHKUSER's config, and then "Rebuild" QMT? I installed from the CentOS 5 ISO. I simply don't want to check the MX for any e-mail on these particular servers.I'd rather the client get bounces for those e-mails, so they can clean up their lists. Michael J.
