[SLL] joined web forum and mailing list(s)

[Jeremy C. Reed]

I am looking for a web forum software that is well integrated with mailing 
list(s). So I can use the forum entirely via email and others can use the 
forum entirely using the webpage interface. I guess this would be like 
Yahoo Groups. (I was also told that Google Groups also allows posting to 
mailing lists. And I also see the gmane.org web interface for reading and 
posting to lists. So maybe something like that.)

I am not talking about the feature where you click a checkbox on webpage 
or enter an email address on the webpage to get emails sent.

Any suggestions?

I see vBulletin has a newsgroup add-on that also supports fetching mail 
and sending email (in addition to NNTP).

By the way, I'd prefer not using a SQL backend or PHP. But okay.
