I have been trying to get mail flowing to AOL for months now.... I finally managed to figure out how to get an SMTP log from my send connector. The log contained the following:
attempting to connect ,+,,<,220-mtaig-mbc05.mx.aol.com ESMTP Internet Inbound,<,220-AOL and its affiliated companies do not,<,220-authorize the use of its proprietary computers and computer,<,"220-networks to accept, transmit, or distribute unsolicited bulk",<,220-e-mail sent from the internet.,<,220-Effective immediately:,<,220-AOL may no longer accept connections from IP addresses,<,220 which no do not have reverse-DNS (PTR records) assigned.,>,EHLO mail.<REMOVED>.net,<,250-mtaig-mbc05.mx.aol.com,<,250-STARTTLS,<,250 DSN,>,STARTTLS,<,220 2.0.0 Ready to start TLS, *,,Received certificate *,1F75F1B43AEDCCA6B206A8D8CA35D87FC37F7A95,Certificate thumbprint>,EHLO mail.<REMOVED>.net,<,554 The security certificate was issued by a company you have not chosen to trust.,>,HELO mail.<REMOVED>.net, -,,Remote
It seems to not like the certificate on the AOL server.... How in the world do I fix this?
Thank You
