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 is</font><font size="-1"><font size="-1">
especially important for web clients which are using frames
(like SquirrelMail) or would otherwise spawn multiple
connections to the IMAP server.<br>
<br>
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.<br>
<br>
I've used the old imapproxyd, as well as Perdition, for this. I
have not tried nginx, so cannot speak to that.<br>
<br>
I hope this is useful information,<br>

Hello,<br>
<br>
the documentation on performance of Horde/Imp: <a
href="https://www.horde.org/apps/imp/docs/PERFORMANCE"
moz-do-not-send="true">https://www.horde.org/apps/imp/docs/PERFORMANCE</a>
recommends installing an imap proxy , e.g. the one from <a
href="https://squirrelmail.org/download.php"
moz-do-not-send="true">https://squirrelmail.org/download.php</a>
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.<br>
<br>
Does such an imap-proxy make things faster for a webmail client?
Is nginx-imap-proxy or anything else better than
squirrelmail-imap-proxy?<br>
<br>
Greetings<br>
