Hello all,
I'm sending this to both qmail-ldap and qmail mailling lists since it's
a feature originally from qmail, but in a qmail-ldap install. Excuse me
if i should have sent this to only one of the lists.
Basically i'm using qmail-ldap with simscan as an alternate qmail-queue.
I started noticing that sometimes i'd get an huge amount of data, like
1+GB, in the temp dir that simscan creates for scanning the messages,
and that happens although i have set ~/control/databytes to 10MB.
>From the qmail docs, i read that databytes is enforced by checking the
actual message size written to disk, and not by counting the ammount
while in transfer by qmail-smtpd.
Basically my doubt is if databytes is enforced by qmail-queue and not
qmail-smtpd, meaning that although there is no message delivery, and
originating a bounce, the message is actually accepted in full for
processing, possibly leading to a DoS (fill the entire fs).
If that is the case, is there a way to configure qmail to prevent this?
Thanks in advance,
Hugo Monteiro.
