+
+If you happen to have accounts on multiple IMAP and/or POP servers,
+you may find managing all the authentication settings inconvenient and
+error-prone. The account-hook command may help. This hook works like
+folder-hook but is invoked whenever you access a remote mailbox
+(including inside the folder browser), not just when you open the
+mailbox.
+<p>
+Some examples:
+
+<tscreen><verb>
+account-hook . 'unset imap_user; unset imap_pass; unset tunnel'
+account-hook imap://host1/ 'set imap_user=me1 imap_pass=foo'
+account-hook imap://host2/ 'set tunnel="ssh host2 /usr/libexec/imapd"'
+</verb></tscreen>
