[issue10839] email module should not allow some header field repetitions

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

Committed.  It is almost never the right thing to do to allow duplicates of unique headers, but an application that does need it can create a policy subclass and override the header_max_count method.
