Re: SMTP Auth - Ldap server
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi I'm trying to SMTP Auth, but the incoming mail server and the outgoing mail server are two different machines, that is, if I want the pop pass and the smtp pass to be the same, I need to sync the two passwd files. Mantaining the two different passwd files on the machines could lead to inconsistency, so I've thought the only way is installing a Ldap server. Do you know any other way to share passwd? yp, nis, ... (but never used that) Do you know a howto to auth pop3 and smtp with ldap? There are some possibilities: Use a pop and smtp server which works with PAM, then you just have to drop your pam_ldap.so into the pam.d/ files.. If you use courier for pop/imap it can handle ldap natively, and postfix for smtp can do this via sasl... And a howto transfer the passwd file to a ldap server? I guess there are some existing scripts, but if you can't find one, it should be a very short perl-script, some kind of splitting passwd-lines and assigning rows to ldap-attributes and add them as whole object into the directory... regards -- \\\ ||| /// _\=/_ ( @ @ )(o o) +oOOo-(_)-oOOo--oOOo-(_)-oOOo--+ | Markus Schabel TGM - Die Schule der Technik www.tgm.ac.at | | IT-Service A-1200 Wien, Wexstrasse 19-23 net.tgm.ac.at | | [EMAIL PROTECTED] Tel.: +43(1)33126/316 | | [EMAIL PROTECTED] Fax.: +43(1)33126/154 | | FSF Associate Member #597, Linux User #259595 (counter.li.org) | |oOOoYet Another Spam Trap: oOOo | | ()oOOo[EMAIL PROTECTED] ( ) oOOo | +\ (( )--\ ( -( )-+ \_) ) /\_) ) / (_/ (_/ Computers are like airconditioners: They stop working properly if you open windows.
Re: Postfix and SASL
I'm having some trouble getting Postfix SMTP auth working. I'm using unstable postfix and postfix-tls on testing, with unstable libsasl2 and libsasl2-modules. Whenever I try to send a message from my mail client (KMail) on another box, I get this in /var/log/mail.log: snip/ I suspect that postfix is trying to use the wrong socket, or something like that. I did a netstat -ap, and found that saslauthd is indeed listening on /var/run/saslauthd/mux. I'd really appreciate any ideas anyone has on this. The problem is, that smtpd runs in chroot in standard-debian-packages, so it cannot access /var/run/saslauthd/mux. Either you move postfix out of chroot or you link the saslauthd-socket into the chroot (only works with hard-links, so chroot and /var/run/saslauthd must be on the same partition) or you tell saslauthd to put the mux-file directly in the chroot. regards -- \\\ ||| /// _\=/_ ( @ @ )(o o) +oOOo-(_)-oOOo--oOOo-(_)-oOOo--+ | Markus Schabel TGM - Die Schule der Technik www.tgm.ac.at | | IT-Service A-1200 Wien, Wexstrasse 19-23 net.tgm.ac.at | | [EMAIL PROTECTED] Tel.: +43(1)33126/316 | | [EMAIL PROTECTED] Fax.: +43(1)33126/154 | | FSF Associate Member #597, Linux User #259595 (counter.li.org) | |oOOoYet Another Spam Trap: oOOo | | ()oOOo[EMAIL PROTECTED] ( ) oOOo | +\ (( )--\ ( -( )-+ \_) ) /\_) ) / (_/ (_/ Computers are like airconditioners: They stop working properly if you open windows.
Re: Problem with squirrelmail-update
Had the same problem. I had to manually edit config.php. Here are the steps I took: 1. Backup up config.php 2. Run conf.pl 3. open config.php and the backup, then do a step-by-step comparison Not sure where the problem was. Sorry, but I have several users who check their mail via SquirrelMail and did not have time to research, just keep working it until it was fixed. There is a bug report on this at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=190923 I think it has something to do with the themes, but am not sure. I'll send you my config.php if you like. Thanks, it work's now. The only differences are the themes, I've ignored them and used the new statements, and the new config.php has a newline at the end, but that shouldn't be the problem I think... For some reason, I also had to reboot my workstation. I don't think that was the problem . . . but Netscrape had basically lost it and I could not clean it otherwise (Mandrake 8.2, Netscape 7.x).

This means too that you'll need 72Mbit at least of raw bandwith just to sustain the traffic. Now to take more real world values, that's means that the number of email on the fly needs to increase as the remote server bandwith will the bottle neck. Some interesting mail server tests, look at postal test program and results, and i'm sure Russel Coker will comment on this. Just a thought too: as you have only one file to send, ramFS it. I dont know if any of the MTA's support sendfile() but it'd be interesting to see the gain brought by the decrease of context switching (using sendfile) instead of read(fileh), write(socket), which may means more concurent connections. We can say that SMTP has an overhead of about 30%, so you need a 100MBit connection at least. Probably that isn't the problem. If you use the system only to send this one mail you could think about mqueue on ramdisk or so which will increase your performance slightly. All of this without the mail to resend etc..etc.. The consideration: remove the attachement and send it as a link to download (which is most of the time prefered by users especially when they read their email by modem and receive a 1 meg mail), then the figure looks better to me...

Re: 400 000 mails in 12 Hours
Jean-Francois Dive wrote: That's interesting: 400.000 email in 12 hours = 9 mail a second sent. which means 9Mbytes of data per seconds, assuming that you ahve a pipe of at least 1Mbyte (8Mbit) to each remote end server, which you obviously wont... This means too that you'll need 72Mbit at least of raw bandwith just to sustain the traffic.
