Anyone had a fix or know a direct contact for someone at xtra to discuss email issues? root(a)sophia:/home/icepick# telnet mx1.tnz.mail.yahoo.com 25 Trying 124.108.96.67... Connected to mx1.tnz.mail.yahoo.com. Escape character is '^]'. 421 Message from (60.234.68.30) temporarily deferred - 4.16.50. Please refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html Connection closed by foreign host. root(a)sophia:/home/icepick# 1 in every 5-10 attempts go through. When mails do finally go through they are getting lost or added to spam folder, I cant find my mail server listed on any blacklists at all so can only suspect that yahoo has some local blacklist? Obviously this is a concern as clients aren't receiving invoices thus getting suspended after 3rd warning, then calling up to say they haven't received any info from us. I've tried sending from different email domains but problem persists, I'd suggest they've perhaps blocked my MX? Xtra business complex faults suggest I can fill out a form which gets submitted to yahoo team, who will then send me another form to get my domain whitelisted, but they suggest I will have to do this for all 2000 domains on this one specific host.
