Hi!
I have no FQDN, so I want my Exim to send my IP address in HELO command
when delivering outgoing mail. RFC2821 (4.1.1.1) say that it should be.
The remote_smtp transport has the following option:
helo_data=[${readfile{/var/run/local-ip}{}}]
File /var/run/local-ip contains my current dynamic IP address.
This works well, until Exim delivering mail with TLS.
Here is transcript of SMTP session:

('@' has been changed with '#' by mail editor)
So, after STARTTLS Exim issues second EHLO with $primary_hostname. I think
it's a bug.
(Mail still delivering correct in my case, so it does not annoy me)
BTW, above log has been resulted with exim -v option. After each SMTP
command that has been sent by Exim there was <CR> symbol (^M). There was
no such symbol after SMTP commands sent by remote server. Maybe it's a
minor bug...
