Joseph,
>1 million+ email?
1. what time frame ? (I assume per day)
2. you mean emails or connections ?
I don't think that a single ASSP instance is able to process 1 million
(the math prevents this) emails a day if any DNS or content check is
enabled or any DB is used.
Even 1 million connections (request at the MainThread -> transfer to
SMTP-Worker) a day will be the absolute upper limit for a single instance
(realistc are 750.000).
I think it is realistic to split the (1M) workload on a minimum of ten
assp instances.
problematic are - independend from the count of the used assp instances :
- the used DNS servers - depending on the check setup, it is possible that
a single mail requires more than 200 DNS queries (SPF, URIBL, DNSBL,DKIM
....)
- the database server - HMM/Bayesian could cause more than 1000 SQL-
select statements per mail
you will need a DNS-server farm that can answer 200 million requests a day
(~2.000 per second)
and you'll need a database cluster that is able to process 1 Billion SQL -
statements a day (~10.000 per second)
not to forget your MTA('s)
If we think a bit more about - Virusscan, Attachment check (forget
OCR,DCC,Razor and Archive) .... such checks requires time
This seems to be a nice challenge. I don't know it exactly - but IMHO
there is nobody on this planet who has such experiences with ASSP.
I hope you are not an ASSP starter ! And don't forget - a day has only
86400 seconds!!!!
