Re: [courier-users] filtering mail in a backup-mx
My solution: I have set up the backup mx system as usual and then do a esmtpd stop. A simple script (executed once a few minutes) tests availability of the primary mx system (just connect, HELO and QUIT). If the primary seems down, esmtpd start gets executed. When the primary is there again, esmtpd gets stopped. That's a nice idea! However, nobody answered my original question. I still want to be able to filter mails which aren't delivered locally. This does also apply for mails which will be aliased to an adress at another host.

Greets, Manuel From courier man page: enablefiltering This configuration file enables the global mail filtering API for selected mail sources. This file, if it exists, contains a single line of text that specifies which kind of mail will be filtered. The possible values are: esmtp Enables global mail filtering for mail received via ESMTP. local Specifies that mail received from logged on users, via sendmail, and mail forwarded from dot-courier(5) will be filtered using the global mail filtering API. uucp Specifies that mail received from UUCP will be filtered. If you want to specify more than one source of mail, such as ESMTP and local mail, specify both esmtp and local, separated by a space charac- ter. Note: The global mail filtering API is described, in detail, in the courierfilter(8) manual page. This is NOT the traditional user-controlled mail filtering, such as maildrop(1). A global mail filter is a daemon process that selectively accepts or rejects incoming mail, based on arbitrary criteria. I have file '/etc/courier/enablefiltering' with one line: 'local esmtp' and everything is filtered via clamcour installed as global mail filter. Keep in mind that global filtering cannot alter emails! Global filters just accept or reject email. This is good for virus checking and not good for spam ( at least for me ).

This works great so long, but I'd like to pipe all mails through spamassassin and clamassassin. A setup using maildrop and xfilter already exists from the primary mx, but how to implement a filter for mails which are just queued and not delivered locally? Any ideas? Yes.

He's right, unless your backup MX can reject mail for non-existent users at your domain instead of accepting it, so you could bounce it later creating backscatter. -- rgds, serge - Take Surveys.

I'll admit, I have a backup MX at the site where I work, but that's only for political reasons. A backup MX's job is to accept mail when your primary system can't, but remote sites are going to queue mail and retry delivery anyway. You're not going to hurt site reliability by taking down you backup MX. In practice, backup MXs are just spam targets these days. Most sites that still have them don't protect them as well as their primary systems, so that's where many spammers deliver their mail. Drop it and concentrate your efforts on one system. You'll be happier with the results. - Take Surveys. Earn Cash.

You're not going to hurt site reliability by taking down you backup MX. Two things here: 1. On your own backup-mx, YOU can control how long messages are queued and whether or when they are bounced. 2. YOU can re-deliver waiting messages when YOU want. So when you re-awake your primary mx, you just courier flush on the backup mx and the messages are there. In practice, backup MXs are just spam targets these days.

A simple script (executed once a few minutes) tests availability of the primary mx system (just connect, HELO and QUIT). If the primary seems down, esmtpd start gets executed. When the primary is there again, esmtpd gets stopped. That combines both, availability in case of a failure and backscatter-protection. cu, Bernd -- Wenn du eine helfende Hand brauchst - du findest sie am Ende deines rechten oder linken Arms. pgpS1IVPL9juc.pgp Description: PGP signature - Take Surveys.
