Hello,

I notice that quite a few hosts today try to start TSL session with my
server while I am trying to deliver mail to them (remote delivery not
smarthost service).

Here's a snippet from the session (the real size of the message to be sent
is 5KB, don't know where 10905190 is taken from):

SMTP>> EHLO lists.lc-words.com

waiting for data on socket
read response data: size=75
  SMTP<< 250-ESMTP Server Ready
         250-SIZE 10905190
         250-DSN
         250-STARTTLS
         250 TLS
157.150.184.102 in hosts_avoid_tls? no (option unset)

SMTP>> STARTTLS

waiting for data on socket
read response data: size=37
SMTP<< 220 Server ready Ready to start TLS
Initialized TLS
Calling SSL_connect
SSL info: before/connect initialization
SSL info: before/connect initialization
SSL info: SSLv2/v3 write client hello A

The hosts I am having problem with are verzion.net and bellsouth.net.
Anyone else seeing this? I have not experienced such behaviour before.
Exim 4.66 my end. Thanks!

Warm regards,
