Hi apologies for what will seem a daft question I'm getting problems with my mail provider who is using dovecot. I've loaded Dovecot on a 8 core ARMHF SBC version 2.2.33.2 on Ubuntu 18.04. The SBC is headless. and the load looks very light and only needs to store/cache 4GB of mail Can I use Dovecot as a buffer between my mail providers Dovecot servers and the several IMAP mail clients on my own network ? ie, so Dovecot would mirror the mail on my account with my mail provider, So my local dovecot server downloads mail and caches/stores on the local SBC and all the local users use IMAP from that, instead of from my mail provider. Can I import the same directory structure as help on my mail providers server ? I'm trying to avoid the timeout problem I get when using IMAP from my mail provider. Can it be done ? and can you withstand the questions on configuration, I haven't used Dovecot before so its a vertical learning curve Thanks -- Best wishes /73 Richard Bown Email : richard at g8jvm.com HTTP : http://www.g8jvm.com ###################################################################### Ham Call: G8JVM .

So namespace remote { ? location = imapc:~/.cache ? prefix = Remote} ... } or mail_location = imapc:~/.cache imapc_username = username imapc_host = hostname etc. See https://wiki2.dovecot.org/MailboxFormat/imapc
Many thanks for all the replies on this. It has given a lot to consider, now for some intense reading .
