1) Are any of you out there running miniQmail / QMQP?
2) What's the final word on which is recommended: multiple inbound SMTP
servers, or a series of QMQP servers? (The goal is high volume / high
availability).
For the latter, here are the two configs I'm considering:
Internet
|
| smtp
|_____________________________________________
| |
| MXa | MXb
_|___ _|___
|miniQ| |miniQ| ...
|_____| |_____|
| |
| qmqpc |
|______________|______________________________
___|_____ ___________
| qmail/ | | RAID |
| qmqpd |---| -queue |
|_________| | -Maildirs |
| |___________|
| NFS
______________________|______________________
| |
| |
_|___ _|___
|qmail| |qmail| ...
|_____| |_____|
| | DNS round robin
| pop | pop
|______________|______________________________
|
|
Internet
Here's the other config:
Internet
|
| smtp
|_____________________________________________
| |
| MXa | MXb
_|___ _|___
|qmail| |qmail| ...
|_____| |_____|
| |
| NFS |
|______________|______________________________
___|_______
| RAID |
| -queue |
| -Maildirs |
|___________|
| NFS
______________________|______________________
| |
| |
_|___ _|___
|qmail| |qmail| ...
|_____| |_____|
| | DNS round robin
| pop | pop
|______________|______________________________
|
|
Internet
Notes:
1)For the moment, both POP sides are the same (I'm not sure what other
POP options exist).
2)The first uses miniQmail; the 2nd does not.
3)The first has a "master" qmail server. The second are pure peers,
offering better availability.
Is the 2nd option even possible with qmail? Any and all educated input
is more than welcome. How do some of you very large sites operate?
Thanks!
Dave
