Barry, I had this issue some months ago. I persisted with contacting Yahoo and filling out their form(s). I was asking them to whitelist the IP address(es) of my mail server. Eventually my mail started flowing again (although I still haven't had an official response from Yahoo to say so). Their spam filters are very harsh and I still have a lot of email ending up in XTRA user's spam folders. Problem with this is most XTRA users don't realize they have a spam folder! There is no point in talking to anyone at XTRA as they are in the dark as much as we are. -----Original Message----- From: Barry Murphy [mailto:barry(a)unix.co.nz] Sent: Thursday, 4 October 2007 12:46 p.m. To: Blair Harrison Cc: nznog(a)list.waikato.ac.nz Subject: Re: [nznog] Continued problems with xtra email 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...

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.
