Title: Limiting email attachment Sizes in Qmail.
Post by: Ashley SHaw on April 01, 2003, 01:34:23 PM

Hi there everyone,

I have searched the forums for a solution to limit users qmail attachment sizes (not just for webmail), but it has been to no avail. I have a 64k dedicated connection to the net that is being clogged by irresponsible users. I am going to implement SquidGuard or/and DansGaurdian with SpamAssasin, this combination will make a great difference to the bandwidth problem, but the users are still mailing large attachments. Is there a way to limit users to e.g.1Mb attachments? If so does it require extra software or can Qmail itself be configured to apply these limits?

Thanks alot in advance!!   ;-)

Cheers
Ashley in South Africa

in the /var/qmail/control directory you can create a file name databytes, it will fix the maximum size of an outgoing message (take into account the mime enveloppe for your attachement size limit -+=25%)

I think you'll find you can do:
/sbin/e-smith/db configuration setprop smtpfront-qmail MaxMessageSize
/sbin/e-smith/signal-event email-update

Where is the maximum message size in bytes.

Any other ideas???
I've tried both these methods and it still won't change the attachment size limit.
Am running e-smith 5.1

Thanks in advance.
