Not your common or garden server....
My feeling is that the MTA is a relatively small (even insignificant)
part of the overall burden of doing large mail systems. Other
significant issues (off the top of my head) are:-
- back end mail storage
- back end retrieval
- spool (and back end) disk access (filesystem, raid etc)
- user dbs etc
- dns
Brad Knowles reckons he can do a million or so ISP customers on a
single bsd box under sendmail with modified (index cache) mbox storage
[NB from memory - I think that was in his verbal comments but canot see
that in his paper]
