As near as I can tell, the # charector is legal in the local-part of an address. http://tools.ietf.org/html/rfc5322#section-3.2.3

I'd like to use it for my VERP seperator, ie myaddress#verpco...@mydomain.com - however when I try to configure Postfix to accept it, I run into a problem in that it is used as the comment charector.

Is there a way I can specify it as the default VERP seperator?

As a followup, I found I could use # as the default recipient delimiter, so it would work for incoming. But no other VERP config would accept it.

Since this is a low volume server, I went ahead and used an smtp_command_filter to fix the issue. I convert all characters I may wish to use a seperator into the standard +
/^RCPT\s+TO:(.*)[#!-\+\|\?](.*)/ RCPT TO:$1\+$2
