CentOS - Jan 2011 - mail problems after setting up lynx for https with c_rehash

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:-

   **********************************************

   ----- 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
