I've noticed lately that when I load mutt (defaulting to my Fastmail.fm INBOX) or when switching from another mailbox back to the INBOX, that the time to display due to fetching message headers takes quite a while.
I'm using IMAP and have a headers directory created in my /home folder which is populated with entries and the following in my .muttrc: set header_cache="~/.mutt/headers" The headers directory is permission 755 and the directories within are 700. I've got ~20,000 messages in the INBOX, but other mailboxes (for mailing lists) have more messages but are evaluated and headers fetched much faster. Just looking for some things to investigate that I may have overlooked. This is on a Mac if that makes any difference and using mutt 1.5.21. Thanks. -- Trey Sizemore t...@fastmail.fm
