Recommendations for "Maximum number of connections per IP address"

[Chrisa]

Greetings,
Is there a document that provides some sort of 'rule of thumb' recommendations for "Maximum number of connections per IP address" in regards to the "Server-Wide Mail Settings".

I understand that as this number is increased it will load cpu, memory etc and that each configuration/situation will be unique, so I'm not looking for definitive answers, just a guideline that would get close to the best value depending on my configuration.


I found this guide, but it does not seem to go into recommendations.

Using Plesk v. 12.5.30
Installed IMAP/POP3 server Courier-IMAP

Thanks

i use:

Maximum number of connections = 250
Maximum number of connections per IP address = 50

50 might seem a lot, but in its standard setup thunderbird imap opens 5 simultaneous connections. So an office with 10 users will open 50 connections from the same ip addres.
