yes

OK. Thanks very much - I'll follow that up and post the results in a day 
or two. This is a very recent network (internet) install - three to four 
weeks so it's not like ancient, but I'll check it out and see if there 
is anything newer on their site.

BTW I'm not too sure what you mean by 'proper mime attachments'; I use 
Thunderbird on windoze (as it has two heads) and just clicked attach and 
attach. But anyway I should be able to put things up on my web site in 
the future if needed.
