Actually... I'm left wondering if this mailserver is really meant to be
an IMAP only mailserver or just an IMAP capable mailserver? Most users
like to use POP and keep their mail locally but have the option to use a
Webmail program when away. If that is the case, there are a lot of
things talked about that really are pretty outlandish. Heck, a lot of
ISPs still have a 5meg quota on their users! Yup, one of the larger ones
in this area defaults to that.. a phone call is all it takes to get it
raised, but I can see their point. If you give them 100megs it'll get
filled up. Many users don't even use email except on hotmail or yahoo.
Spammers' dictionaries are constantly finding non-mail user accounts on
my boxes. Mother Nature abhors an unfilled harddisk.
Also, if the school can only afford to use an old machine like this, how
much 'time' can they afford to put into a highly customized system?
There's the learning curve..... and as well, many times the 'person
responsible' changes frequently in a college setting. Having something
which someone else can take over is an important issue. "Simple" is
relative... once you've done it five or so times.. yeah, it's simple. :)
Many of us have to know something about a LOT, and simply don't have the
time to know a LOT about something. Like having a good grasp of
everything from setting up webservers, DNS, email, to building
sites/pages understanding some of the programming languages to doing
tech calls for folks whose "Outlook is stuck", who many times don't know
the difference between Outlook and MSIE! This is said just to point out
the idea of thinking about the 'level' of the posters inquiry and situation.
I think we could easily handle AOL's, MSN's and Yahoo's email with what
has been discussed... but it might take more that a 40G drive... ;)
