I have the following problem.
Some Hotmail/Live.com users who register @ my website don't get verification emails. Exim logfile shows the following:
2015-01-22 19:45:04 1YELoT-0006U2-Su => XXXXXXX@live.com R=dnslookup T=remote_smtp H=mx3.hotmail.com [220.127.116.11] X=TLS1.2:RSA_AES_256_CBC_SHA256:256 DN="CN=*.hotmail.com" 2015-01-22 19:45:04 1YELoT-0006U2-Su Completed
but emails never appear in Hotmail mailboxes.
I have SPF records for my domain, "from" address exists, server has reverse PTR record, server's IP address doesn't exist in any blacklists. No problems with Gmail, Yahoo etc, only with Hotmail.
I use non-existing "reply-to" address. Could it be a problem?
Anyway, if there is a problem with my emails Hotmail should reject them instead of accepting and not delivering. They are just fooling people.
As I understand this problem is not permanent. I have users with Hotmail email addresses, some people get verification email, some not. Today I made several tests but no emails in my Hotmail mailbox.
Is there any way how to get in contact in Hotmail to fix the problem? If not the only solutions is not to accept Hotmail/Live com addresses. :(
