Re: [PLUG] Strange Exim-TLS issue

[Martin DiViaio <scatterbrained@usermail.com>]

What's your mailserver returning in response to the EHLO command?

Chances are, whatever mail program you are using on the laptop can't find 
what it wants to issue the starttls command. (There's a similar issue with 
older versions of Netscape claiming a mailserver can't do ASMTP because 
the mail server didn't return "AUTH=LOGIN" in the response to EHLO.)

Is the gateway running some sort of SMTP proxy?
