[Pkg-exim4-users] Multiple ports and enforcing authentication on just the n

Not the method I'd read - interesting - might try that one instead - it 
looks neater.

Perhaps a little more background will assist.  I work for a small 
company - but we're very dispersed - using technology to its fullest to 
keep in touch.  I might converse in email, over MSN, Skype, and POTS 
with my colleagues during any particular working day.

The server which I'm configuring is based somewhere in a data centre in 
London.  I'm near Bristol.

The main office is only 3 miles away, but its overcrowded already, so I 
get to work from home.  The two Senior managers who I mentioned work 
about 20 and 150 miles away.

Most of the people around here have fixed IP addresses, either singular, 
or a small block (say a /29) so its easy to allow them to relay by 
putting them in the permitted relay hosts.

Wanadoo, however, don't give out fixed IP addresses, and thats why I 
only want to put authentication on the additional port and not on port 25.

Thanks for your feedback - I'll go read README.Debian now. ;-))

Regards
Neil
