Hi everyone. I'm seeing something really strange and I'm wondering if any of you guys have seen this as well. Messages sent from one of my people (using Imail) to Hotmail accounts are being bounced with the 550 relaying denied error. When I check the logs I see this:
10:03 04:16 SMTP-(857d014d035eb158) Info - Found hotmail.com in DNS Cache 10:03 04:16 SMTP-(857d014d035eb158) Connect hotmail.com [63.250.192.46:25] (1) 10:03 04:16 SMTP-(857d014d035eb158) 220 mta1693.mail.gq1.yahoo.com ESMTP ready When I saw this, my first initial thought was that the DNS server my person is using with Imail is incorrectly caching information. As you can see, they are sending to a Hotmail email address, but it's trying to connect to a Yahoo server. After doing a few NSLookups using different DNS servers, I found that any DNS server I use to look up that IP resolves to that Yahoo server. I did a few tests on DNSStuff.com as well and I see that the IP does, in fact, belong to Yahoo, not Hotmail. Has anyone seen this and know why it's happening? To my knowledge, Hotmail and Yahoo aren't connected, but I could be mistaken. Thanks!
