authsenders
Authenticated sender. For each sender included in authsenders: sender:relay:port|user|password qmail-remote will try SMTP Authentication of type CRAM-MD5, LOGIN, or PLAIN with
the provided user name user and password password (the authentication information) and eventually relay the mail through relay on port port. The use of relay and port follows
the same rules as for smtproutes Note: In case sender is empty, qmail-remote will try to deliver each outgoing mail SMTP authenticated. If the authentication information is
missing, the mail is delivered none-authenticated. authsenders can be constructed as follows:

@example.com|generic|passwd
.subdomain.example.com|other|otherpw
mail@example.com|test|testpass
info@example.com:smtp.example.com:26|other|otherpw
:mailrelay.example.com:587|e=mc2|testpass

If the following error is encountered when testing the new certificate the certificate is most likely less than 2048 bits

Usually Let's Encrypt certificates are at least 2048 bits, but encountering 256 bits keys is possible. Correct by specifying the number of bits:

Welcome to Qmailtoaster's Wiki page.

== Background ==
=== Introduction ===

Welcome to the Qmailtoaster wiki. Qmailtoaster is designed to be very stable and easy enough to install that even an inexperienced Linux user can install, operate, and maintain a full blown Qmail MTA.

Everyone is encouraged to find ways to improve Qmailtoaster and to pass their knowledge on to others via the wiki and the [mailto:qmailtoaster-list-subscribe@qmailtoaster.com email list].

This wiki is maintained by Eric Broch and the rest of the Qmailtoaster community as a means of providing a centralized location for assisting all Qmailtoaster users.

=== History ===

QmaitToaster was conceived by Miguel Beccari in June 2002. At the time, Miguel was an IT for Clikka.Com in Udine Italy. Miguel's goals were to provide a very stable rpm based Qmail MTA, and to build a "Qmailtoaster" community of users to support and develop the Qmailtoaster project.

=== Subsequent QmailToaster Maintainers ===

2003-2007, Nick Hemmesch

2006-2007, Erik Espinoza

2007-2011, Jake Vickers

2011-2014, Eric Shubert

2014-Present, Eric Broch

For details on the evolution of the various QMailtoaster packages, see the [[Change Logs]].

There is a good graphic titled [http://www.nrg4u.com/ THE BIG Qmail PICTURE] available in several formats that explains how qmail works. The author does not indicate that is free to distribute, however it is free for personal use. Get a copy for yourself, as it is a handy reference.

Also grab a copy of Sills' [http://www.lifewithqmail.org/ Life with qmail] in whatever format you choose. It too is a valuable reference.
