Hi
I'm using the qmail-queue-patch together with the qmail-scanner and I'm
also thinking about to put some spamfilters before or after the
antivirus scanning.
Then qmail receives a mail through smtp it wait with the response to the
sender that the mail was completly delivered until it has scanned the
mail for virus. If the attachments are big it can take a long time
before it release the connection. And if I add some filters that examine
the mail for unwanted words etc it will take much more time.
Is it ok to let the sending smtp server to wait so long time before it
has processed the mail? For me it sounds like a bad idea to let them
wait. So I'm thinking about to create another queue that the mail can be
placed in first so qmail can tell the sender that it has ben received
and then start to scan and filtering the mail in that queue before it
deliver it to the original queue.
Someone who have any thoughts about a qmail setup like this? Is it a
good idea to queue the message twice or to let the sending server wait?
Andreas
