Can you have per domain quotas and DATABYTES settings?

You can either implement size limits for each mailboxin the domain by using the details at:

marc.theaimsgroup.com or install the QMAILQUEUE patch, qmail-qfilter and createa filter:

#!/usr/bin/perl

my %databytes = (

"example.net" => 5 * 1024 * 1024,

"example.com" => 10 * 1024 * 1024,

);

if (FD, ";

close(FD);

}

foreach my $rcpt (split(/\n/, $ENV{QMAILRCPTS})) {

my $domain = lc $rcpt;

$domain =~ s/.*@//;

if ($databytes{$domain} && $databytes{$domain} < (stat STDIN)[7]) {

exit 31;

}

}

print or exit 53 while(<>)

;close(STDOUT) or exit 53;

The drawback of this last approach is that the client will always receive the not so informative reject message:

554 mail server permanently rejected message (#5.3.0)

Note that DATABYTES must always be larger than any values used on a per domain basis, and a single mail to multiple different domains will be constrained to the smallest databytes value of the destination domains.
