othellotech Posted February 29, 2012 Share Posted February 29, 2012 I've sent and received emails from WHMCS in the last 48 hours without issue 0 Quote Link to comment Share on other sites More sharing options...

I don't run Exim on any of my servers, and the likelyhood that 20 mail servers are down on my side is unlikely ;-) 0 Quote Link to comment Share on other sites More sharing options...
bear Posted February 29, 2012 Share Posted February 29, 2012 Hmm, you could be right. DIG shows an interesting result: 02/29/12 12:11:43 dns 50.116.115.104 nslookup 50.116.115.104 Canonical name: whmcs.websitewelcome.com Addresses: 50.116.115.104 02/29/12 12:11:55 dns whmcs.websitewelcome.com Canonical name: whmcs.websitewelcome.com Addresses: 74.54.136.210 Still doesn't explain why it's only you, however, and that's why I said to look internally. 0 Quote Link to comment Share on other sites More sharing options...

othellotech Posted March 3, 2012 Share Posted March 3, 2012 It's probably unable to do the callback to your mailserver/from-address so treating you as a spammer... # telnet whmcs.com 25 Trying 50.116.115.104...
