Thanks for replies from Kevin and Felix, I could eliminate my problems related to imap connection. I have made mistake inserting “$my_user” in the “set folder” statement. Now, I can receive all the mail messages contained in my mail server. I deeply acknowledge your advices. From now on, I will optimize to shorten the fetching time at the launch of mutt by further setting several variables, because it takes currently long time to complete even in the case of a few numbers of new messages. I hope that mutt can be easily introduced even in my Win10 (32bit) environment, say using chocolatey…

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 = 10000 in 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.
