Umailer is an e-mail sending program, allowing you to send e-mails
from both fake and real addresses from anywhere without the need
for your local ISP SMTP server.
The software features are as followed:

# You no longer need a list of SMTP servers to send the e-mails,
by using a sub part of the DNS protocol called Mail Exchange,
with it you can now send any mail from any known domain on
the internet. A simple thing which makes Umailer extremely
easy to use; while keeping it?s original function to use
static SMTP server, like your ISP, for example.
# Multi Threading allowing you to send you mail faster using
three multi threads.
# SOCKS 4 / 5, allowing you to use a Proxy server to bounce your
connection to the target?s SMTP server, and by that remaining
anonymous, your IP will not be logged!
# Group Send, with it you can create a complete list of e-mail
addresses and send them the same mail all at once.
# POP3 Cleaner, the tool originally comes from the first version
of Umailer allowing you to apply different types of mail box
cleaning filters to help your POP3 accounts to remain junk free.
# MX-Lookup, another tool allowing you to create a full lookup on
SMTP server list of any domain known on the internet.
