[DeleGate-En] ESMTP problems
I'm using Delegate for about one year on different machines and operating
systems (Linux and SunOs5.6).
Delegate as SMTP-Proxy works just fine - but some MTAs seem to have problems
concerning the ESMTP implementation. I've tested versions 7.9.1 and 7.5.4.
Delegate delivers an empty 250 line causing errors.
Whenever the remote MTA gets the empty line without any additional ESMTP
commands it's just waiting and finally a time out occurs.
The only thing I could do was downgrading to version 7.3.0 which doesn't
know about ESMTP at all and forces the remote machine to use SMTP.
