Its really doing things this way round?  There are 2 possible options:-
     1. STARTTLS which is an ESMTP extension, so requires an initial
        EHLO before a STARTTLS command.
     2. ssmtp which would do all the transactions over an SSL/TLS
        channel, including the initial HELO/EHLO


If you want the latter than you must run another instance of exim on a
different port with the -tls-on-connect option.

This is covered in the FAQ -
        http://www.exim.org/exim-html-4.20/doc/html/FAQ_17.html



Alternatively if Communigate really wants to do STARTTLS following a
HELO then it is *really* broken. Either than or you have a really
broken SMTP proxy in the way (Cisco PIX anyone). In either case an axe
is a suitable tool to provide a solution to this problem.
