[vchkpw] Restrict amount of vchkpw authentications
Hi I've got vpopmail 5.2.1 on top of qmail 1.03 on a Solaris 2.7 SPARC machine. Everything is going well. I've noticed, though, that several of my users are abusing my pop3 service, that is, that they are popping their email every minute, 24 hours a day. this has not become a problem for my mail server performance as of yet, but i'm being pro active. It is clearly stated in my aup that checking your mail more than once every 5 minutes is unacceptable, and that once (or less than) every 10 minutes is preferred. I'm wondering if anybody has implemented a method of making vchkpw only allow one authentication per user per 5 minutes.. I'm looking for something that will not silently deny their connection, but something that will actually make their mail client do something like pop up a message, or pop up a username and password window.. just so that the client knows that he's doing something wrong. --- Jeremy Kister www.jeremykister.com PGP: http://www.jeremykister.com/jeremy/public_key.asc ---
Re: [vchkpw] Restrict amount of vchkpw authentications
You might be best off hacking up your popd to achieve this. Have it look at last login time and spit out an -ERR You are popping too often see http://blahblahblah;. Some clients will show this others won't. As a shortcut you could pull some existing data out of mysql and send a nagging email to the abusers...

I don't think there is anything in POP that makes the client pop a warning. Cheapest way is to write something that reads the log file and mail warnings or do your desired actions to offenders.
