[PATCH] make async/require_resolvable_fromhost accept mail from null sender

[Radu Greab]

If async/require_resolvable_fromhost is used, then mail from the null
sender is rejected.

Please check the attached patch: the second part of the plugin will
DECLINE if the first part declined too because of the null sender.


Thank you,
Radu Greab
