If by "B", you mean they are permanently assigned one of the IP addresses from your allocated block (ie: they have a static IP), then it's not a problem. For a lot of ISPs that "grew up" from small operations (which is most of them), there comes a point when the static IP's become too prescious; I have heard that Best Internet (www.best.com) is a heavy FreeBSD user that has gone this route; they recently stopped offering static IP's (but they haven't installed a DDNS soloution, yet), so they are pretty much cutting themselves out of the small business (ie: transiently connected business) market when the business outgrows 3 or 5 or however many POP3 maildrops and needs their own server. Or if they don't outgrow it, but they don't want their company mail going out to where they don't control before it comes back. DDNS buys you a large part of your address block back. > Also, I have designed a Mailserver to run at MX35 to act as a FAILover > with a large que storage if I need to take take the mail system offline > or the RAID system dies somehow or things just get too busy.

That won't be a problem until you have 30,000 customers (everyone should have such problems 8-)). > Just to mention, I am using Qmail with Maildir delivery to overcome the > file locking problems of sendmail across an NFS link. This is really more of a problem with the Mlocal mailer more than anything else, I think. Sendmail doesn't do final delivery itself. You could hack /usr/libexec/mail.local to use lock files rather easily. 8-). > The setup is ALL FreeBSD except for the DHCP servers (If only FreeBSD > could run Sun/Solaris Binaries) and of course the Netapp devices.

What's wrong with the ISC DHCP on FreeBSD, that you need Sun/Solaris binaries?
