- With reference to my question:
- |Is anyone prepared to recommend a mailer which will run under MSDOS
- |(or Windows) and support both PC-PC mail via ethernet and co-exist
- |with a Unix/Internet mail system - i.e. will exchange mail between
- |the PC and the Internet via a SunOS machine.
-
- I received the following replies - thanks to those who helped out.

- I think you'll get a lot of message about POP3 and IMAP2...
- Here's a list of programs and sites:

- Serving PCs and Workstations Using a Central Mail Server on an Internet
- - ------- --- --- ------------ ----- - ------- ---- ------ -- -- --------
-
- There are advantages to collecting mail destined to PCs and workstations
- on a central server, to be turned over to the PC or workstation on
- demand:
-
- - - Your PC or workstation may be down quite a bit and less network bandwidth
- and less of the processing resouces of the sending computer are used
- if the computer receiving your mail is ready.
- - - Some people use more than one PC or workstation to read mail.
- - - A PC or workstation may not have the resources to store all the mail
- you receive.
- - - It can make your e-mail address more like other users'.
-
- The easiest way to "implement" this is to run the central mail server like
- any multi-user system: let people sign on to it and use some mail utility.
- Then PC and workstation users can use "terminal sessions" to sign on to the
- central mail server and read their mail. This has the disadvantage of
- making the PC and workstation users learn and use the central mail
- server's procedures.
-
- SMTP, the "internet" mail protocol used to deliver mail between multi-user
- systems only supports mail transfer initiated by the sender. Other
- protocols have been devised to allow a workstation or PC to request
- transfer of mail, thus able to make use of a cnetral server. These
- include the published protocols POP (probably not used anymore), POP2,
- POP3, IMAP2, and DMSP.
-
- POP, POP2, POP3:
- These are rather minimal and are designed to be so. The three are similar
- but not enough alike to be interoperable. They are basically designed to
- identify the user by username and password, to transfer the mail from
- server to PC or workstation and to delete the mail transferred. It is
- assumed that SMTP will be used to send mail. Messages can be retrieved
- individually, but the only information you can get about a message without
- transferring it is its length in bytes-- useful for PCs with limited
- storage.
-
- POP2 and POP3 are still used a good deal. POP3 has a couple of optional
- extensions: one to avoid sending passwords, and one to aid in reading
- bulletin boards.
-
- IMAP2:
- This is similar to the POP family, but also gives clients a way to do
- string searches through mail that still resides on the server. This is
- designed to allow the PC or workstation to be more selective as to which
- mail will be transferred. The POP protocols, on the other hand, are
- designed for simpler server software.
-
- DMSP (aka PCMAIL):
- PCs and workstations can use this protocol to both send and receive mail.
- The system is designed around the idea that each user can own more than
- one workstation; however, the system doesn't seem to handle the idea of a
- "public workstation" very well. The PCs and workstations are assumed to
- hold state information about the mail, a directory so to speak, and when
- the PC or workstation is connected to the server, this directory is
- updated to "reality".

- Two reasonable PC user agents are POPmail and nupop, both free and
- available in the usual PC SW archives. If you want to know more, ask
- and I will tell you what I can.
-
- If you have a Novell network, the combination of Pegasus mail and a
- Charon mail gateway is hard to beat. These are both free, also.
