AUTH PLAIN test script
See [1] (more information at [2])
First we need to compute the authentication string for the PLAIN authentication (this requires perl with MIME64 module installed):
# Don't forget to escape any '@' in the perl string or it shall be interpret as an array variable!!!
perl -MMIME::Base64 -e 'print encode_base64("\000jms1\@jms1.net\000not.my.real.password")'
# AGptczFAam1zMS5uZXQAbm90Lm15LnJlYWwucGFzc3dvcmQ=
Example of script:
