serialmail is a collection of tools for passing mail across serial
|
|
links. It works with qmail: you use qmail to deliver messages to a
|
|
maildir, and then serialmail to deliver messages out of the maildir.
|
|
|
|
serialmail is designed to handle three common types of mail delivery
|
|
between a dialup computer and an ISP:
|
|
|
|
* Delivery to the ISP. The dialup computer sends all outgoing mail to
|
|
the ISP.
|
|
|
|
* AutoTURN delivery from the ISP. After the dialup computer makes an
|
|
SMTP connection to the ISP, it automatically receives an SMTP
|
|
connection back from the ISP if there is any new mail for it. This
|
|
provides the same power as ETRN but does not require a special
|
|
client.
|
|
|
|
* User-controlled delivery from the ISP. A user with a shell account
|
|
can switch from qmail-pop3d to serialmail without pestering the
|
|
sysadmin. The user can also decide whether undeliverable messages
|
|
should be left for POP retrieval or bounced back to the sender.
|
|
|
|
serialmail supports SMTP, including ESMTP PIPELINING, and QMTP.
|
|
|
|
serialmail uses ucspi-tcp/tcpclient for networking. It can also be used
|
|
with future UCSPI clients for transparent compression, IPv6, etc.
