A bit of both.  From dumpasn1.cfg:

OID = 06 0A 09 92 26 89 93 F2 2C 64 01 03
Description = rfc822Mailbox (0 9 2342 19200300 100 1 3)

OID = 06 07 02 82 06 01 0A 07 1C
Description = emailAddress (0 2 262 1 10 7 28)

OID = 06 09 2A 86 48 86 F7 0D 01 09 01
Description = emailAddress (1 2 840 113549 1 9 1)

(and rfc822Name is from the GeneralName which only has an overall OID, or at
least one for every extension in which it appears).

There's also a:

OID = 06 09 2A 86 48 86 F7 14 01 03 2E
Description = mailRecipient (1 2 840 113556 1 3 46)

although I'm not quite sure what that is.

Peter.
