Parameters

Return values

Note
the first character in mailbox matching any of the characters in $imap_delim_chars is used as a delimiter.

This is necessary because the rest of neomutt assumes a hierarchy delimiter of '/', which is not necessarily true in IMAP. Additionally, the filesystem converts multiple hierarchy delimiters into a single one, ie "///" is equal to "/". IMAP servers are not required to do this. Moreover, IMAP servers may dislike the path ending with the delimiter.
