I want to have a seperate user/password database for each domain and ideally host them in such a way that some are bound to the same IP and others get individual IPs. This means that the client pop software will need to be configured with a domain portion of the account to identify which virtual domain the client wishes to pop for. To this mix, I want to add virus scanning and ideally a webmail interface. I expect to have over 20,000 accounts after adding up all domains. The main ISP domain will probably have in excess of 18,000 accounts very soon. These accounts will be coming over dialup ports at 56K and I expect not more than 150 users to access their mail simultaneously. I was thinking this could be accomplished with a mix of qmail, neomail etc but although my mail administration experience is decent, up until now I've only worked with sendmail on linux and solaris. So if any of you are running this sort of configuration could you please give me some pointers to get started? The server I am considering using is a Dell PowerEdge 2550 with 1GB RAM, P3-1.26GHz and 36GB of disk space on a RAID 5 volume. I am considerring adding a second processor to cope with the antivirus scanning load. All tips and comments would be greatly appreciated, Thanks! -Ahsan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
