A client has contacted my saying one of their clients/suppliers are receiving bounce backs, and has asked me to check out why. I've checked the logs and it doesn't look as though they should/are being blocked, however the emails are failing. The bounce back they receive says: 451 4.4.1 reply: read error from mail.incommingserver.net.
New Member We are getting the following warning errors for email sent to a customer: Final-Recipient: RFC822; [emailprotected] Action: delayed Status: 4.4.2 Diagnostic-Code: SMTP; 451 4.4.1 reply: read error from ci.wa.us. I am trying to figure out what this actually means, and who exactly is having the problem. I tried testing the targeted email using network-tools.com and it worked fine. So, I am somwhat stumped on how to proceed from here. chipsafts, Jan 3, 2008 #1 falko Super Moderator ISPConfig Developer Any errors in your mail log? falko, Jan 4, 2008 #2 chipsafts New Member http://www.logsat.com/spamfilter/forums/get_last_post.asp?TID=5543 Jan 3 11:03:35 net sendmail[21954]: m03J31ep021951: to=<[emailprotected]>, delay=00:00:34, xdelay=00:00:31, mailer=esmtp, pri=211171, relay=mail.ci.wa.us.
