I would like our 150+ users to be able to send attachments to each other and small groups without limits, but at the same time they should not be able to send this "couch for sale" 6MB jpeg to "all_users<at>..."
Any way to do this? I don't think it's possible with the standard admin tools, but a script or some other solution might allow to fine tune attachments?
Any help/ideas are greatly appreciated.

quite simply i would reccomend that all users had an attachment limit, email wasnt originally design to transmit large files. kerio doesnt have any feature like this(attachment limit on a rules basis) that i can tell it just has an overall outgoing message attachment limit or none

your best bet is to set a reasonable limit on attachments (10-15MB is usually good nowadays) and then tell people that files bigger than that have to be transmitted in other ways (hint rapidshare.com or yousendit.com are good methods particularly to multiple people)

thank you for your reply.
the point is, that I don't want to touch the possibility that a single user sends a large attachment to another user. she/he should just not be able to send it to a large group (valid alternative: put it on the file-server and just mail the link).

The issue here is:

1: Email it to a group, and you get it copied all the times that there is users - without them maybe even wanting the file. Big backup hurdle.

2: Share it via a fileserver: One file, backup is much less! Educate your users! Or tell them the price of the email 'solution'...

1: is what I have
2: is what I would like to have.

Not all users can be educated. some will never learn and usually they are spamming the biggest attachments to all users.

Seems that I have to live with that fact.
I will continue shouting on them (and buy bigger HDs) but I'm still convinced that at least a warning messagge e.g.
"You're about sending attachments to a large user group! Do you really want to do that?" would be a nice feature.

best option would be to set the outgoing limit for everything

people learn very fast then Smile

voice of experience talking, sure someone asked me why they couldnt send a large attachment and got upset about my answer and was trying to demand it released...

my answer, please can i have £5-8k to implement a larger raid system and approriate backup solution. i think they understand why i am forced to limit attachment sizes and seeing as the file is on the server anyway in most cases... they dont even have to attach they just type file x is in folder y on the server

ok so everyones scenario is different but its worth letting people know that lots of external mail servers will not accept attachments over a certain size (i think its 10MB)
for there users so its better to play safe so they get a bounce message sooner rather than waiting anything up to 12 hours for a mail server to send a wierd message about not being able to recieve
