Hi,
Dovecot Wiki states that mail process (IMAP/POP3) is able to handle multiple
client connections as the same time to save CPU and memory resources (client_limit
> 1). Although this approach is not recommended due to latency and probably
security issues, it does help increase the overall capacity of a mail server. Is
it possible (or planned) to add a feature such that mail client connections of the
same user from a same IP are directed to a same mail process? In most cases, such
connections come from a same mail client (e.g. in Thunderbird, each mailbox is a
connection). The end user (human being) can work on one mailbox at a time, the
latency will be non-obvious. And since all data being processed belong to the same
user, security is a non-issue.
Thanks,
Hi,
a features like this should be added:

The ability to save/restore IMAP connection state. This would allow
getting rid of most of the long running memory-hungry idling IMAP
processes by keeping the connections in a small number of IMAP-idle
processes where they wait for something to happen. This also allows
moving IMAP connections between servers. This could also improve
performance of some webmail systems by having the webmail server
remember the state as a string and then be able to quickly restore it
with another IMAP command.
