Unfortunately, I have found that many Web programmers don't bother to
read RFC's and find out what characters are allowed in email addresses.
Many sites will not accept a "+" in your username. I think the old
default qmail delimiter, "-", is a better choice for those just now
switching to recipient_delimiter use. Another good one would be ".".
To name one, I tried to get automobile insurance with GEICO, a large
insurer in the USA. If I had access to my old virtual_alias_maps I
could find many more who rejected the "+".
