10.12 The format of configuration

In Mew 6.1, configuration format of "mew.el" is improved. You can use a new format as well as the old format.

• - In the old format, sometime "." appears. In the new fomat, no "." appears at all. For instance, you can write ("foo" "bar") instead of ("foo" . "bar").
• - In the old format, a numeric port is specified as string. An example is "25". In the new format, you can write it as integer. An example is 25. The string is still valid. An example is "smtp".
• - In the old format, the cases and the keys of ‘mew-config-alist’ are written as string. In the new format, you can specify them as symbol.

Here is an example of the new format:

(setq mew-config-alist
      '((home
         (imap-server       "imap.example.org")
         (imap-ssl          t)
         (imap-ssl-port     993)
         (smtp-server       "smtp.example.org")
         (smtp-port         "submission"))))

Compare this with the following old one:

(setq mew-config-alist
      '(("home"
         ("imap-server"   . "imap.example.org")
         ("imap-ssl"      . t)
         ("imap-ssl-port" . "993")
         ("smtp-server"   . "smtp.example.org")
         ("smtp-port"     . "submission"))))

Again, the old format is still valid. You can also mix the new format and the old format.
