The following characters are defined as legal for the local-part of
an email address:
* All alpha numerics (A-Za-z0-9)
* The characters ! # $ % * / ? | ^ { } ` ~ & ' + - = _
* The character ., non-repeated, as long as it is not first or
last
So, for kicks I created a new local user with the username:
#test{!user%}^
and then sent a test email to it. Postfix complained:
warning: Illegal address syntax from munge[munge] in RCPT command:
#test{!user%}^(_at_)covisp(_dot_)net
So, just out of curiosity, which characters are legal for procmail?
