|How does the Qmail plug-in work?|
#cd /var/qmail/binNow make sure that f-protd is running and you have scan-mail.pl running with the -server option. Now you should be able to make a connection to 127.0.0.1:11200 for scan-mail.pl and 127.0.0.1:10200 for f-protd.
#mv qmail-queue qmail-queue.orig
#cp /usr/local/f-prot/tools/f-prot-qmail ./qmail-queue
#chown qmailq.qmail qmail-queue
#chmod 4711 mail-queue
The f-prot-qmail program will make a copy of each message in /tmp, contact the Mail Scanner at port 11200 and supply the Mail Scanner with the message. When the Mail Scanner has finished rewriting the message, the f-prot-qmail program will start qmail-queue and supply it with the rewritten message.
The Mail Scanner will add a header line to your e-mail, "X-Antivirus: Scanned by F-PROT Antivirus (http://www.f-prot.com)"
If F-PROT Antivirus detects an infection in a message or attachment, the Mail Scanner will try to neutralize the threat. If the infection is removed, the Mail Scanner will only defang the message or attachment. If, however, F-PROT Antivirus fails to remove the infection, the message or attachment will be removed, and an appropriate message will be appended to the e-mail. The Mail Scanner will take no action if the attachment is found to be clean. In the case of a runtime error, the Mail Scanner will defang the message. Defanging involves changing the filename extension, and thus removing the danger of a user running the attached file by double-clicking it.
The Mail Scanner can be configured to generate backups of all incoming mail by supplying it with the -backup switch. To generate backups of infected messages only, use the -quarantine switch. This will cause the Mail Scanner to create a directory MMDD/ under /usr/local/f-prot/backup (where MM is a number representing the month, and DD is a number representing the day of the month), and a file underneath there in the format of unix-time.pid. That file will contain the original message before the Mail Scanner scanned it.
