hi
i would like some opinions regarding hardware requirement for a mail server and a proxy server for a network with 4000 users
i would although know if sendmail and squid are suitable for this job
thanks

Well, that all depends on your traffic levels. Sendmail and squid are going to be able to handle anything you throw at them, if they're properly configured and on the right hardware.

You'll need a fairly substantial system with that many users, of course.

Where I work we have about 3000 people at our main building who's email goes through the one server. It runs exim I believe with spamassassin and squid. I believe the server is a dual xeon 3.0 with 2GB ram and 500GB of storage.

thank's guys

my job is to buy two severs (one for mail and another for proxy) and i need to know what hardware can handle 4000 user
so more examples are welcome
thanks

Did you ever try contacting a vendor and asking them? They would know this info. If they don't or can't get it for you. I would not buy a server off of them.

i'm afraid if i ask a local dealer about this they will try to sell me a more expensive server that i would need in reality

To be honest, if you are handling 4000 users. You should go with a company like IBM, HP or Sun. I am not sure what you mean by local dealer. But I would not use PC class hardware for a production server.

i would like some HP Proliant servers i just don't know how many processors, memory and hard disk can do the job
for the proxy server i thought that an HP Proliant Ml110 with one PIV processor at 3 Ghz, 2Gb DDRAM, a 36 Gb SCSI HDD for the system and a 72GB SCSI HDD for the cache would be nice

for the mail server i would choose an HP Proliant Ml150G2 with one Xeon processor at 3 GHz, 1,5 Gb RAM, 36Gb SCSI HDD for the system and a 146 GB SCSI HDD for /home for the mails
i'm just not sure if that's enough or it is too much
any suggestion is welcome
thanks
