What does this TLS error mean?

Hi folk

I've got 2 Ironport set up with preferred TLS to and from all domains and I've got a self signed certificate installed. TLS is OK to and from some receivers but one of them generate "Info: ICID 4884545 >> 454 TLS not available due to temporary reason (missing server certificate?)" when they send mail to me.

Any ideas?

Regards

Fredrik

Re: What does this TLS error mean?

My assumption would be that some of the senders are not trusting your self signed certificate.  I believe you will need a

publicly trusted certificate for TLS to work across the board.
