Re: [cobalt-users] amount of users

[Jeff Lasman <jblists@xxxxxxxxxxxxx>]

What else are you doing on the RaQ?  How often are these 3,000 users 
getting their email?  How much disk-space do you have?  A RaQ doing nothing 
else should be able to handle the load.  But users logging in might notice 
slight delays in logging in.

There's no limit on the number of accounts.  But authentication based on 
the /etc/passwd and /etc/shadow files is going to be 
sloooooooooooow.  You'd definitely want a better POP program, one optimized 
for heavy usage, with it's own password database.

3,000 email addresses, at 5,000,000 bytes each (5 megabytes) adds up to 
15,000,000,000, or 15 gigabytes of disk storage.  Plus the space you need 
for temp files, depending on how many people are accessing email at the 
same time.

I'd probably do this on a high end RaQ3 only if space were really the 
imporant consideration; otherwise I'd probably want to use a high-end Intel 
based solution.  Can a file server handling 3,000 email accounts afford to 
ever be down?  Do you need redundant drives (RAID)?  Do you need hot swap 
redundancy in both drives and power supplies?  For 3,000 users, I'd 
probably want to say yes.
