Hi List, I am not sure it's related but after I ran c_rehash over my ssl certificate directory I am having email delay problems. 1. my thunderbird client now regularly times out and tells me the smtp server is not available - a retry always works - this never occurred before. I do use TLS for the smtp server on port 25 for my connection. 2. another mail server that regularly sends me mail reports:- ********************************************** ** THIS IS A WARNING MESSAGE ONLY ** ** YOU DO NOT NEED TO RESEND YOUR MESSAGE ** ********************************************** The original message was received at Mon, 24 Jan 2011 21:12:16 -0800 from relay07 [10.183.136.126] ----- Transcript of session follows ----- <rkampen at reaching-clients.com>... Deferred: 403 4.7.0 TLS handshake failed. Warning: message still undelivered after 1 minute Will keep trying until message is 5 days old The mails arrive just fine a bit later - related?? I have checked the load on the server - low I have checked maillog and can see nothing different or unusual running centos 5.5 on 2.6.18-194.26.1.el5 BTW lynx with https is working just fine now Not sure where to look next - any ideas or suggestions appreciated TIA -------------- next part -------------- A non-text attachment was scrubbed...
