Re: email free...
While I have not looked at the new code releases, I do know that previously the vpopmail directory was defined in config.h and used for pop and smtp based on that. Vadddomain also knew to use that same path as well. I'm sure it could be modified to look anywhere with minimal effort...perhaps have it get the value from /var/qmail/users/assign for the path instead of pre-defining it at compile time. This seems to me a far more flexible way to accomplish what your asking, however could add some latency as it did the lookup each delivery or pop3 check. For the short term, you can always put the directories on any disk volume/partition you want and symlink them back to the /export/vpopmail/domains directory. While not the most appealing solution, it is stable. Right now I have my maildirs on an external scsi attached raid. I have the OS on it's own drive, and the queue itself on another fast scsi drive.

Re: email free...
Yes, it would most likely be better to have multiple drives set up on a fast channel controller handling different domains / subsets of domains. Incidentally, if you change the directory vpopmail uses for the domain, are there any inherent bugs (software that doesn't ask vpopmail where the maildirs are, etc.)?? /var/vpopmail/01/domain1 /var/vpopmail/01/domain2 /var/vpopmail/01/domain3 /var/vpopmail/02/domain1 /var/vpopmail/02/domain2 /var/vpopmail/02/domain3 This would let you mount /var/vpopmail/01 on one drive, and /var/vpopmail/02 on another. - Original Message - From: "Delanet Administration" <[EMAIL PROTECTED]> > IMHO, I'd worry more about I/O than disk space.

Re: email free...
It's typical that you can oversell usage in mail servers the same as you do dialup lines or t1's etc etc. I have 13k users in 300 or so domains on a qmail server with 10mb quotas each, and currently it uses about 11.5gb of space. I have my maildirs on a 30gb external raid. A number of users check mail so frequently that they use very little space. A large number receive little in the way of volume. There are only about 200 or so out of my 13k that are over quota, and I usually run pretty loose on quotas.. One could put a hard limit on it and not have to worry. IMHO, I'd worry more about I/O than disk space. Having a large slow ide may hurt more than a fast scsi. -- Stephen Comoletti Systems Administrator Delanet, Inc. http://www.delanet.com ph: (302) 326-5800 fax: (302) 326-5802 Jacob Scott wrote: > Not to rain on anyone's parade: 20K accounts@1MB each is already 20gigs... > on a 10gb hdd- so, if you want to allocate 1Mb/account, maybe 7K accounts? > Or buy another hard drive, yeah. =P > > Jacob > > -Original Message- > From: kbo [mailto:kbo]On Behalf Of Ken Jones > Sent: Thursday, August 03, 2000 11:52 AM > To: [EMAIL PROTECTED] > Subject: Re: email free... > > Ben Beuchler wrote: > > > > On Thu, Aug 03, 2000 at 12:19:50PM -0500, Ken Jones wrote: > > > > > > Hi, I've a server with this hardware configuration: > > > > AMD- K6 - 500Mhz, 64Mb RAM, 10Gb HD (IDE).

What about a ramdisk for Kernel, etc, and the database on some IDE RAID =) spd! Jacob

On big domain with lots of users ? Some big performance hits with vpopmail in order of importance 1) quota checking 2) mysql instead of cdb 3) roaming users No numbers on them tho.
Re: email free...
Hahah, Good point! I'd go for a second hard drive. Throwing in a sansdisk IDE solid state 400M drive would also boost performance ALOT. They go for about $800 or so.

RE: email free...
Not to rain on anyone's parade: 20K accounts@1MB each is already 20gigs... on a 10gb hdd- so, if you want to allocate 1Mb/account, maybe 7K accounts? Or buy another hard drive, yeah. =P Jacob -Original Message- From: kbo [mailto:kbo]On Behalf Of Ken Jones Sent: Thursday, August 03, 2000 11:52 AM To: [EMAIL PROTECTED] Subject: Re: email free...

It's a gut feeling based on systems I've worked on and talking to other people about thier machines. Another number to throw into the mix ;] on most free email sites, only 10% to 20% of the accounts are active. (based on that - i'm probably overstating the amount of 20K) We did some measurements with a similar machine as above. About the same hardware except it had 128Mram. Only doing outgoing email, for newsletter type mail. It was able to sustain about 750,000 emails per day. It ranged from 500K to 1.1M. Ken Jones

Does any one have any numbers on vpopmail's incoming perfomance ? On multiple domains with few users? On big domain with lots of users ?
