OK, I'll add that to my TODO list. I guess I need to figure out how to
parse regexps. :)

Either way, the regexp flag sounds perfect. It may be a bit complicated, but
of course does not have to be used.

Actually, brackets are legal in email addresses. The full list of legal
characters is (as far as I know):
a-z A-Z 0-9 @ / : . # [ ] - \ _ = , !
On my keyboard, that doesn't leave much and I can't guarantee the
remaining characters aren't legal either. I'm not sure I want to use a
tilde as a wildcard simply because it's available -- it's not very
intuitive.
This just occurred to me -- what about creating a new flag to allow
regular expressions? For example, recipient-whitelist-file would use
the existing logic but recipient-whitelist-file-regexp would allow
regular expressions and wildcards. That way, nearly everyone would
continue using the existing system but if someone needed more
flexibility they could create a second file and use the new flag. Or
does that sound too complicated?

I'm pretty sure that square brackets are not valid email address

Given this, maybe some sort of scheme where [] would delineate wildcards.
Regular expressions may not be so easy, since [] are meaningful inside
them,
but perhaps something simple like and asterisk representing zero or more
any char, and a question mark representing a single any char.
Like this:
[EMAIL PROTECTED]
would match:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
but not [EMAIL PROTECTED]
and
[EMAIL PROTECTED]
would match:
[EMAIL PROTECTED]
but not [EMAIL PROTECTED]
etc.

Yes, starting a line with @ is the only available wildcard. I thought
about doing more, just like you're asking about, but I got hung up on
the complexities.
Email addresses allow so many characters that it's hard to find a good
way to indicate a wildcard. I was also afraid that no matter what I
tried to implement, it wouldn't work for all situations -- the best
solution would be to just use full regular expressions. Then I became
concerned that using regular expressions would cause problems if someone
just filled the file with email addresses and they wound up being
matched as regexps. That's where my thinking ended and I went with the
current solution.
What do you think? I'm open to suggestions.

Thanks for adding the recipient-whitelist-file feature. I have a
quick
question: Is starting a line with @ the only wildcard ability?
What I would like to do is have something like this:
#--recipient-blacklist-file:---
@mydomain.com
#--
#--recipient-whitelist-file:---
[EMAIL PROTECTED]
#--
The intention is for spamdyke to block all email coming in for that
domain,
except anything matching [EMAIL PROTECTED] (eg
[EMAIL PROTECTED],
[EMAIL PROTECTED], etc)
Is this possible now, or perhaps in future versions?
