dovecot 2.2.27 welcome plugins script

[Carlos R Laguna]

Hello everyone,

I am trying to send a mail to newly autocreated users, using the welcome 
plugins, however, i am get unable to pipe user information  correctly to 
the script, acording to the wiki the scripts are called just as the 
quota warnig scripts.

Also, every time that a try something new i have created a new 
user...... is a pain. what can i do to test this without to create a new 
user after any little change?
