connection. I have atleast 3000 pop and 1000 concurrent imap connections
on the server.
Um, I think you're confusing concurrent connections with connection rate. You'll only be talking to LDAP for a quick query during session initiation... Your connection numbers aren't really that big ;)
One more issue with nginx 0.8.34 is that when auth-fails on the real
server the nginx returns "BAD: internal server error"
The email clients are not able to interpret this error.
Can I configure nginx to pass on the actual message from my cyrus server
"NO LOGIN failed"
Thanks
