[Dovecot] Configuration advices for a 50000 mailboxes server(s)

[Frank Bonnet]

hello

Thanks for your answer , MY problem will be IMAPS connections
I dunno how much I will have but it would be possible that we'll
have 4000/6000 imaps concurent connections during working hours .

POP3 users will be very few
