Is there anyway to change a Linode IP's CNAME entry? If not, the SMTP servers set up on Linode VPS's should be used with caution–who knows if other mail servers have similar policies and will block incoming mail accordingly. > Verify that your rDNS contains a name that includes 'mail', 'SMTP', 'relay', or 'MX'. If they don't see 'MX' or 'mail' or the like in the address, they apparently assume it's spam and block it. Mine resolves to a linode member address, of course. Everything works great now.Īpparently, godaddy does a reverse-DNS on your IP. I called and after some leading of the first-line tech in the right direction, she unblocked my linode IP. But they relented and unblocked me this morning.Īt Godaddy, I just had to keep working at it, and getting pissed.ĭescription I had the same issue - outgoing email would send fine to seemingly everywhere but GoDaddy. Then again, perhaps not.Īt Godaddy, I just had to keep working at it, and getting pissed. Perhaps someone who had this IP before me was sending spam. Whether you get stuck in this situation is just luck. It's hard to imagine an outfit less savvy than Earthlink, but this is one. Only the more savvy ones just unblock stray requests like mine. The other defers delivery, which means that I don't get a failure back, so my accounts think the mails are received but they're not.īoth messages refer you to their unblocking web form – like many ISPs. Just fyi, for each mail, the logs show entries from the two servers on the MX list, one rejects because it sees spam. But they relented and unblocked me this morning. It went downhill from there.ĭescription Thanks guys. They wanted 'mail' or 'smtp' in the name to make it _look_ like a mailserver.

They started off by saying they didn't like my hostname. I submitted an unblock request and have had the most bizarre runaround with them. I ask them what kind of spammer do they think would waste an hour on the phone with them? They suggest I submit another form, but the form tells that I've already submitted the request.ĭescription I'm having trouble with Godaddy and I wonder if anyone else is, and what they did about it.Įxcept that Godaddy () blocked one of my outgoing mails to an email customer of theirs. They even block my mails to the unblock people. (When I run gethostbyname() I get my IP, and when I run gethostbyaddr() I get my hostname.) They won't say what they use to check on name resolution. They claimed the IP didn't resolve to my hostname. They wanted 'mail' or 'smtp' in the name to make it look like a mailserver. The accounts I handle are successfully sending and receiving mail to and from all over.Įxcept that Godaddy () blocked one of my outgoing mails to an email customer of theirs. I recently set up a mail server on linode, created a CNAME for the hostname, and set the rDNS to give out this name, which is the same postfix is using. I'm having trouble with Godaddy and I wonder if anyone else is, and what they did about it.

Incoming mail server go daddy
