Parsing of mail addresses

Addresses indicate the senders and recipients of messages and correspond to either an individual mailbox or a group of mailboxes.

    type local_part = string

Usually the user name

    type domain = string

The domain of the mailbox

    type addr_spec = local_part * domain option

The pair `local_part@domain` as O'Caml type. The domain may be missing.

    class mailbox : ?name:string -> string list -> addr_spec -> object .. end

A `mailbox` has a name, optionally a route (not used nowadays), and a formal address specification.

    class group : string -> mailbox list -> object .. end

A `group` has a name, and consists of a number of mailboxes.

    type t = [ `Group of group | `Mailbox of mailbox ]

The union of `mailbox` and `group`

    exception Parse_error of int * string

A parsing error. The `int` is the position in the parsed string

    val parse : string -> t list

Parse a list of addresses in string representation, and return them as list of mailboxes or groups.

Examples:

- `parse "gerd@gerd-stolpmann.de"` returns a single `mailbox` without name and route, and the given spec
- `parse "Gerd Stolpmann <gerd@gerd-stolpmann.de>"` returns a single `mailbox` with name and spec, but without route
- `parse "abc@def.net, ghi"` returns two `mailbox`es without name and route, and the two specs. The second address only has a local part, but no domain.
- `parse "g:abc@def.net, Me <me@domain.net>;, gs@npc.de"` returns one group `g` with members `abc@def.net` and `me@domain.net`, and another `mailbox` `gs@npc.de`.

Old-style naming of mailboxes is not supported (e.g. "gerd@gerd-stolpmann.de (Gerd Stolpmann)" - the part in parentheses is simply ignored.
