[Bug 405733] [NEW] sendEmail fails when using SMTP PLAIN Authentication

[Dave]

Public bug reported:

Binary package hint: sendemail

Expected: sendEmail sends the mail out using the specified server and
credentials for SMTP AUTH

Reality: The server responds with a syntax error when PLAIN
authentication is used -- which is the default if the server supports
it. If the server response shows that the server does not support PLAIN
but LOGIN, everything works fine.

Speculation: sendEmail does not generate the AUTH PLAIN string correctly
before sending it to the server (line 1917 in /usr/bin/sendEmail). Or
the 1&1 mail server is buggy.

Workaround: Make LOGIN the default (in /usr/bin/sendEmail: exchange
lines 1914-1919 with lines 1921-1928, but preserve "if" and "elsif")

Note: TLS isn't used in this example (no SSL::Leay installed), but a test showed no difference with or without TLS.
Note: The AUTH PLAIN string has been altered (well, it contains username&password as base64), so I replaced it with a random string, but preserved the equal signs at the end. Also, all credentials and mail adresses have been altered.
