Summary: check_smtp problem with TLS+AUTH using Exim
Initial Comment:
When checking SMTP AUTH via TLS using Exim, you'll get
a "503 AUTH command used when not advertised" error if
trying to use AUTH without (re)sending EHLO _after_ the
TLS negotiation. RFC 3207 (4.2) says: "The client MUST
discard any knowledge obtained from the server, such as
the list of SMTP service extensions, which was not
obtained from the TLS negotiation itself. The client
SHOULD send an EHLO command as the first command after
a successful TLS negotiation." The attached patch does
just that in order to make the check_smtp plugin work
with TLS+AUTH using Exim.
