[PATCH] SMTP Modifications

From: Steve Holme <>

Dear all,

In preparation of adding NTLM support and other features to SMTP I have
enclosed a preliminary patch to performs the following:

* Modify the order of the preferred authentication method to: AUTH CRAM-MD5,
AUTH LOGIN then AUTH PLAIN. AUTH PLAIN should be the last as it is less
secure than AUTH LOGIN as the username and password are sent together -
there is no handshaking between the client and server like there is with

* Correct the line length of line 1359 as this was 80 characters long.

* Tidied up some spacing issues after functions and between variable
assignment operators.

Any comments or suggestions welcome. If folks are happy with this, I will
work on the next patch to add some of my new features over the next couple
of days such as:

* Add the ability for authenticated connections to send the initial response
from "AUTH mechanism [initial-response]" in a second command, after
receiving a 334 to the "AUTH mechanism" from the server.
* Add support for the AUTH parameter in the MAIL command which is mostly
used by servers relaying emails to other servers. For example: MAIL

Kind Regards
