qmail queue

[Sumith]

Hello All   Excuse me if this question has been repeated a lot of times...   I've install qmail from memphis rpms. also VPOPMAIL 4.9.8-1   How can I know how many concurrent qmail deliveries are taking place on my qmail server, both qmail-local and qmail-remote   I have applied the qmail-concurrent-patch, and big-todo-patch   There is no concurrencylocal and concurrencyremote presently in /var/qmail/control   If the default is 10 for concurrencylocal and 20 for concurrency remote (which lwq says)....what would be the safe number to increase this to on my PIII 800 , 512 MB RAM, IDE hard disk handling about 500 virtual domains.   I hope that some one helps me to clear my doubts.   Regards Sumith
