Each IMAP server has its own quirks.  As much as we tried to stick to standards, it doesn't help much if the IMAP server doesn't follow the same principles.  We have made some work-arounds for some of these servers.  If you would like to use them, please select your IMAP server.  If you do not wish to use these work-arounds, you can set this to "other", and none will be used.     bincimap    = Binc IMAP server     courier     = Courier IMAP server     cyrus       = Cyrus IMAP server     dovecot     = Dovecot Secure IMAP server     exchange    = Microsoft Exchange IMAP server     hmailserver = hMailServer     macosx      = Mac OS X Mailserver     mercury32   = Mercury/32     uw          = University of Washington's IMAP server     gmail       = IMAP access to Google mail (Gmail) accounts     other       = Not one of the above servers

Command >> 9     # select

This is the delimiter that your IMAP server uses to distinguish between folders.  For example, Cyrus uses '.' as the delimiter and a complete folder would look like 'INBOX.Friends.Bob', while UW uses '/' and would look like 'INBOX/Friends/Bob'.  Normally this should be left at 'detect' but if you are sure you know what delimiter your server uses, you can specify it here.  To have it autodetect the delimiter, set it to 'detect'.

If you have already set the hostname and port number, I can try to automatically detect the mechanisms your SMTP server supports. Auto-detection is *optional* - you can safely say "n" here. 

Try to detect auth mechanisms? [y/N]: y     # yes (auto)

Testing none:           SUPPORTED Testing login:          SUPPORTED Testing plain:          SUPPORTED Testing CRAM-MD5:       NOT SUPPORTED Testing DIGEST-MD5:     NOT SUPPORTED  What authentication mechanism do you want to use for SMTP connections? none - Your SMTP server does not require authorization. login - Plaintext. If you can do better, you probably should. plain - Plaintext. If you can do better, you probably should. cram-md5 - Slightly better than plaintext. digest-md5 - Privacy protection - better than cram-md5.  *** YOUR SMTP SERVER MUST SUPPORT THE MECHANISM YOU CHOOSE HERE *** If you don't understand or are unsure, you probably want "none" 

none, login, plain, cram-md5, or digest-md5 [none]: login     # select "login" on this example

SMTP authentication uses IMAP username and password by default.  Would you like to use other login and password for all SquirrelMail

SMTP connections? [y/N]: n     # no (use IMAP authentication)
