[Declude.JunkMail] OT: Attachment sizes

2004-08-04 Thread David Fletcher
We have never set message size limits on our servers.  Now it is
becoming an issue.

Is there any sort of standard for maximum message sizes?  This is for
hosted customers and I'd like to be reasonable, but I don't think
allowing them to receive 18meg + messages is necessary.  (I just shook
my head when I saw this one after hearing the question: Why is my
Outlook locking up?)

What limits do you all use?

Thanks for the input.

I think you found your answer... You want your maximum message size to
be small enough that the message won't crash your customer's MUA, and
large enough that the vast majority of cases are handled without
trouble.

Another way to look at it is based on the maximum size of their
mailbox (if any). How many messages is _reasonable_ in such a mail box
on average. Divide it out and cut it in half so that twice as many
messages would fit... remember average means half of the time you're
bigger and half of the time you're smaller ;-)

If you can't find a happy medium for your customers then take your
best shot, publish it prolifically, and include an alternate mechanism
for them to use (such as FTP). This is a problematic solution - but by
definition so is the problem.

Hope this helps,
_M

PS: On our system, which is small and populated mostly by power users,
we don't have any such limits - but we do charge for storage and
throughput ;-)

David, 

We limit around 10MB.  It has worked well.  That not to say several folks 
havent tried to email 50+MB files..

Definitely SpamAssassin.  If you want these tests and more, check out the
