The /etc/aliases file uses email address notation as defined in
Internet standards such as RFC 822. When you have a chance to look
up this 27-year old document, then you will discover that it
describes a recursive language.
For this reason, the contents of /etc/aliases cannot be parsed
correctly with regular expressions
In case you aren't aware of this, /#.*$/ is a regular expression.
