list of emails of mailing lists

[deeptech71 at gmail.com]

For example, you can write to this list via the 
freebsd-questions at freebsd.org email, but questions at freebsd.org is also 
recognized as an email for this list. This can't be the same with 
freebsd-doc ->doc and cvs-doc ->doc, that would be ambiguous. Could 
someone please direct me to a 100% precise list of emails that are 
recognized as a mailing list emails?
