Ah! Thanks, you've described your problem now rather than your beleived solution. We can address the problem in a way that I think is better (and have done many many times). Mail comes into you (spam, whatever). You filter it at one of N boxes with equal value MX records. N can be 1, 2 is nice for redundancy, but if you need, you add more. Better to make the machines robust enough to deal with whatever your run. DNS and MX records allow's mail delivery to be extremely robust. All these front machines use a mailertable entry to send all your mail back to the qpopper machine, which now only gets mail from your filtering machines. This mail server machine has minimal load (it gets filtered mail and puts it in spools). The edge/filtering machines work like hell. If it gets too high, you can scale laterally with more machines. Odds are than a 4CPU DL580 with multiple disks will handle the highest loads unless your anti-spam software is brutally inefficient. You may want a non-spam filtering machine to handle SMTP for internal users. Since Eudora (annoyingly) doesn't look at MX records for its relay, you can just set an A record for this machine. Don't allow access from the outside through tcpwrappers, ipfilter/ipfw, your router, firewalls, whatever. > Homer > > > > > Quoting Homer Wilson Smith ([EMAIL PROTECTED]): > > > Running, > > > > > > Linux 2.0.38 or 2.4.x, > > > sendmail 8.8.8 or 8.12.x > > > procmail 3.22 > > > qpopper 4.0.2 > > > > > > Is there any way to run qpopper on one machine and sendmail/procmail > > > on multiple other machines, and allow sendmail/procmail to deliver mail to > > > drives that popper can read without corrupting mailboxes? > > > > > > Pointers to RTFM encouraged as well as direct answers.
