Dilyan,
In my own experience, an IMAP proxy is helpfulfor webmail clients, in
that the proxy can maintain a persistent connection to the IMAP server,
thus saving the time & CPU cycles which would otherwise go in to
bringing up and tearing down the TCP/IP sessions. This isespecially
important for web clients which are using frames (like SquirrelMail) or
would otherwise spawn multiple connections to the IMAP server.
The best performance may be had by placing the proxy on the web server,
so the bulk of the connections can happen via Unix sockets, or localhost
TCP/IP connections. Then just a handful of IMAP connections happen
between the web and IMAP servers.
I've used the old imapproxyd, as well as Perdition, for this. I have
not tried nginx, so cannot speak to that.
I hope this is useful information,
-nic

Hello,
the documentation on performance of Horde/Imp:
https://www.horde.org/apps/imp/docs/PERFORMANCE recommends installing
an imap proxy , e.g. the one from
https://squirrelmail.org/download.php which ceased deveopment decades
ago. The idea is that horde/imp/the-webmail-client connects to the
imap-proxy and this should make everything faster.
Does such an imap-proxy make things faster for a webmail client? Is
nginx-imap-proxy or anything else better than squirrelmail-imap-proxy?
Greetings
