Im sure you'll get answers for all the MTA's so maybe the best thing is |
| 13 |
just to describe what we do. |

I work for an ISP, and we have mail servers supporting several thousand |
| 16 |
users. For this setup we are using qmail + vpopmail + MySQL. We looked at |
| 17 |
LDAP too and concluded it was an ugly beast ;-) Our vpopmail account |
| 18 |
details all live in MySQL - separate read and write database servers help |
| 19 |
spread the load (we replicate between servers). vpopmail uses maildirs by |
| 20 |
default - this means we can NFS mount delivery folders across machines |
| 21 |
without worrying about file-locking, etc. This also means you can spread |
| 22 |
POP3/IMAP traffic across several machines if you want. |
| 23 |
|
| 24 |
We also have three servers dedicated to spam and virus filtering - those |
| 25 |
run daemonized spamd and clamav (we are using a local DNS zone to |
| 26 |
round-robin spamd connections so the load is again spread across all three |
| 27 |
filtering servers). |
| 28 |
|
| 29 |
We are also using squirrelmail and qmailadmin to provide a web mail |
| 30 |
interface and a web postmaster interface for domain accounts. |
