A friend and I both have email with our website hosts (I'm with JoneSolutions he's with HostingMatters I think). We noticed earlier this week that my email to him wasn't getting through. He sent one to me, I replied and he received it but when I try directly from mine it neither ends up in my sent items nor received by him. If I send it from my Gmail account it works fine.
Are we right to assume this is a reception issue? There is nothing in his junk folder, nothing in his webmail and we've checked for blocked addresses and even put my address into his 'whitelist' on his cpanel, but still nothing.
Is there anything else we can check for before contacting our respective hosts ? Or are we right to assume that my hosts may have been added to a blacklist at some point ?
We both use IMAP, both use SSL and both use Windows Live. We've also tried recreating the accounts using the respective cpanel auto configure options but there is no change.
