I have configured postfix + mysql + courier-imap (pop3d) to maildir.
I have mare than 75.000 mailboxes today, working...
What the chances that i move my mailboxes to maildirs, to put the
pop3d to listen for connections, and the pop3d do not do the job???
Today i have (more or less), 100 simultaneos connections (popper). Is
good the pop3d performance? There are some initialization flag to
daemons number to start up?
courier's pop3d reads every single message completely on
every login to calculate the size (with CR/LF instead of CR).
This could keep your filesystem really busy with 100
You could patch this away and send back the wrong size based
on filesize only, just like qmail's pop3d does since ever.
Fetchmail had a problem with this ~2 years ago, but recent
versions and other clients dont care.
