Re: [courier-users] Turning accounts into honeypots

Ale That way I can also get rid of the verbose output of DEBUG_LOGIN=2, so long as 535s stay limited to the usual, innocuous attempts. A filter would shoot on sight at honeypot's authenticated posts, and direct them to some script that either recognizes the spam template or keeps the message quarantined. The idea is to report the compromised web site appearing in the message body, so as to cause some friction. (The bot's IP could also be reported --more easily-- but I'm not sure an ISP would bother acting on it.) -- ___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

You could list authmysql twice, but each instance uses the same config file. pgpAgHtoqnps4.pgp Description: PGP signature -- ___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

Maybe falling over to different auth backends might work but, Sam, it would be really neat to somehow have sane multiple auth options. For instance I would love to have separate imap/pop and smtp auth passwords so if a users incoming mail password is compromised the virus/bot still can't send out using the same account (assuming the user takes advantage of multi passwords). -- ___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

That's already doable with authmysql, authpgsql, or authsqlite. They can execute a custom SQL query. The $(service) variable expands to the service being authenticated. You could customize the query to have something like WHERE username='$(local_part)' AND service='$(service)', and have multiple entries in the table for each service being authenticated, each one with a different password. pgpcwwiNo5yb2.pgp Description: PGP signature -- ___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
