limit email siz

[duke22]

hello just wondering whether there is a way to restrict the size of the email user can receive. I don't mean the actuall mailbox size but the size of the individual emails?

I would assume the limit for the mailbox quota is for the mailbox size isn't it?

thanks for your help

I have not tried this myself (never had the need), but you may want to try creating/editing the Qmail control file:

/var/qmail/control/databytes

Here's the info from 'man qmail-smtpd':

       databytes
            Maximum  number  of bytes allowed in a message, or 0 for no limit.
            Default: 0.  If a message exceeds this limit, qmail-smtpd  returns
            a  permanent error code to the client; in contrast, if the disk is
            full or qmail-smtpd hits a resource limit, qmail-smtpd  returns  a
            temporary error code.
 
            databytes  counts  bytes  as  stored  on  disk, not as transmitted
            through the network.  It does not count the  qmail-smtpd  Received
            line, the qmail-queue Received line, or the envelope.
 
            If  the  environment  variable  DATABYTES  is  set,  it  overrides
            databytes.

I'm not sure if this would include attachment size or just message body size.
