[courier-users] Blowfish for passwd encryption in a postfix-mysql-courier system
Hi, I'm moving a Suse based server: 3000 accounts, MTA: Sendmail, passwd/shadow auth. The new server its Fedora Core 6 with Postfix-Courier-MySQL. SuSe use Blowfish to save the passwords, but Fedora does not recognize this kind of encryption.

Esther Schindler wrote: /***If you could get your CIO (or top management) to understand one thing, just ONE thing, about fighting spam, what would it be?***/ Remember your mailbox next time you vote. And the follow-up: why did you pick that one item? The plan for spam, content filtering, is a chimera. If 'puters can't _understand_ human messages, they cannot distinguish spam and ham either. Full stop. Spamassassin, bogofilter, CRM114 and the like are nice tools in the trench, but won't win the war. Black lists are the most effective protocol-level filter. However, they are not authoritative. For example, Telecom Italia is a big company and every now and then gets blacklisted (Jan, 4 mail-abuse). They got blacklisted for good reasons, e.g. some possessed PCs relaying spam through their servers. Now, if I obey the black list decision, I do a disservice to my customers. So I have to disobey. Such a big company should either keep under surveillance their clients, or officially appoint an external black list. SPF is a generally not used protocol-level filter that allows appointing black or white lists on a per domain basis. It would be very effective if generally adopted. It won't be widely adopted until it is an experimental protocol. IMHO, it's still experimental because the industry cannot make big money with it. Therefore, everybody look at the next silver bullet. If I were good at English, I'd write something better than http://www.openspf.org/Community/Who_Framed_Roger_Rabbit Much spam is the result of criminal actions, such as infecting IT systems and using false identities. Prosecuting those criminals could be even automated, with existing technologies. Technically, spam can be stopped if everybody else want to be responsible for what they send.

[courier-users] filtering mail in a backup-mx
Hi, I use courier-mta at another machine which acts as a backup-mx. It doesn't have any local users, just a few domains in its esmtacceptmailfor. 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?

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. 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. 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 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.
