bash script for email rules

[epixoip]

i'm having kind of a difficult time reading your script, you seem to be adverse to both indentation and POSIX.

anyway, if this does what i think it does, you don't need to use the rule engine for this, nor do you need an external script or program to generate these candidates. this functionality is all built into plus.

examples,

-a 1 usernames domains -k '^@'
-a 1 usernames domains -j u -k '^@ u'
-a 1 usernames domains -k '^#'
-a 1 usernames domains -j u -k '^# u'
-a 1 usernames domains -k '^~'
-a 1 usernames domains -j u -k '^~ u'
