Is there any way to start getting SHA or even MD5 sums in these announcements ? Sourceforge has been cracked a few times so it makes me leary everytime. -- ~Allie D.

Are they in RAID at all? It's looking that most of your high load average is due to waiting on IO. This is solved by adding more drives to increase available IO bandwidth. You should become familiar with two utilities, vmstat and iostat. If you're using a redhat derived linux, install the sysstat rpm to gain access to iostat. Between these two utilities you should be able to figure out where your problems are coming from and how to resolve them. Regards, Tren Esta mensagem foi verificada pelo E-mail Protegido Terra.

[vchkpw] busy try again later error
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I've been running into an issue on our mail server recently. As traffic has been increasing on it, I've been getting the response that I listed in the subject more often, and now customers are also seeing it (busy try again later!). Of course, this response causes any mail clients to prompt for password, making it rather annoying. The closest I can find to the problem is an old message on this list back in 2005 from Gaetan Minet (http://www.mail-archive.com/vchkpw@inter7.com/msg22797.html). That particular fix won't help since vpopmail has it already. Does anyone have some suggestions for detecting the cause of this issue? Server Specs: Dual 1.8gHz Xeon Processors (P4 family) 1gB RAM Software: OS: Slackware Linux 11.0 with kernel 2.6.20.3 vpopmail: 5.4.18 Filesystem: ReiserFS with noatime option I am using cdb user maps with pop-before-smtp. I have 2112 domains on the system (counting aliased domains) and 6034 accounts (counting forwards and aliases). I am also using validrcpthosts, but running generation on a cron every 15 minutes instead of via pipe (pipe method was causing slowdowns on qmailadmin). - -- ___ Michael Johnson 909-740-3156 x3163 System Administrator [EMAIL PROTECTED] PhD Computing http://www.phdcomputing.net/ -BEGIN PGP SIGNATURE- iD8DBQFHDR6KehyONlqb1LIRAt9XAKDV0RD/SWrEbMaHZVtVKl83DIDGDwCg81ko ZA+VLuoTWXmdPLyu7yaNcao= =QXgb -END PGP SIGNATURE-

You could increase the number of allowed pop3 connections though. The default is 40. You can increase it by using the -c xx flag with tcpserver, where xx is your required number of connections.

Our server with about 30K users almost never goes over 40 concurrent connections, and we do have quite a few users checking every minute. Are you sure there isn't some issue with authentication or perhaps I/O that is slowing down the pop connections ? Regards, Rick

Regards, Rick Yes, the processes are a bit overkill, and we maybe have 100 concurrent connections as many of our customers use e-mail as a file delivery service and so utilize the connection for some time when getting messages. I don't believe I remembered to note that the mailboxes are on an NFS mount. The filesystem on that server is JFS mounted with the noatime option. The connection between the mail and file server is on a private switch with the file server being on a gigabit port, and the mailserver on a 100 mbit port. Perhaps it could be some weird locking issues with the cdb files over NFS, but I would think that would have exhibited itself before now when the office staff all connects to get mail. This is a new problem. It started in September and we haven't added many new accounts since then, maybe 100 domains. Nothing mail-related on the mail server, and nothing on the fileserver has changed since before that time. - Michael

If you goto www.clamav.net there is a link to it. I heard they corrected the problem you mention in current, but clam is still way to slow compared to other scanners so I don't use it anymore.

I heard they corrected the problem you mention in current, but clam is still way to slow compared to other scanners so I don't use it anymore. Q Are you using clamscan or clamd/clamdscan? If the former, that's why it's so slow - see if you can switch. Also, what interface to your AV software are you using? Something like qmail-scanner that's a perl script is much slower than qscanq or simscan, which doesn't have the overhead of launching perl with each invocation. One other hint - something I do for all my servers (I use simscan not, but I've also used it with qscanq in the past) is put the scanning directory onto a ramdisk (I use tempfs these days, but a true ramdisk would be even better if you can dedicate the memory to it). It prevents the excess disk I/O overhead that slows the process down, and since it's transient data anyway that shouldn't get through in case of an error, the fact that the scanning space isn't crash-proof is a non-issue...
