1 serialmail is a collection of tools for passing mail across serial
2 links. It works with qmail: you use qmail to deliver messages to
3 a maildir, and then serialmail to deliver messages out of the
6 serialmail is designed to handle three common types of mail delivery
7 between a dialup computer and an ISP:
9 * Delivery to the ISP. The dialup computer sends all outgoing mail
12 * AutoTURN delivery from the ISP. After the dialup computer makes
13 an SMTP connection to the ISP, it automatically receives an
14 SMTP connection back from the ISP if there is any new mail for
15 it. This provides the same power as ETRN but does not require
18 * User-controlled delivery from the ISP. A user with a shell account
19 can switch from qmail-pop3d to serialmail without pestering the
20 sysadmin. The user can also decide whether undeliverable messages
21 should be left for POP retrieval or bounced back to the sender.
