I would like to know how to limit fetching number of mails because it is impossible to complete fetching within the set period of time (imap keep alive 300 seconds).
The server timeout should generally be 30 minutes.However, if you have a **very** large number of mails, the server can time out while fulfilling a single FETCH request. To fix this, you can fetch them in groups. Do this by putting:
set imap_fetch_chunk_size = 10000in your .muttrc. This will perform a FETCH per 10000 messages, which should avoid server timeouts. You can try reducing the number if that is still too big.
What does this MUA copy to the local environment in the IMAP mode? Is this only subject? It would be of great help if someone could advice me.
The headers Mutt requests by default are listed at <http://www.mutt.org/doc/manual/#imap-headers>.
By the way, if you have a large number of messages, you will want to use header caching. See <http://www.mutt.org/doc/manual/#caching>.
% mkdir ~/.mutt/hcache set header_cache = ~/.mutt/hcache You may also want to try out $imap_qresync or $imap_deflate. -- Kevin J. McCarthy GPG Fingerprint: 8975 A9B3 3AA3 7910 385C 5308 ADEF 7684 8031 6BDA
