What, exactly, is being done to validate sender/recipient email addresses during a connection?
I am finding that there are many, otherwise legit, addresses with local portions that are too long. RFC 2821 4.5.3.1 says 64 characters maximum, yet I regularly see much longer (last one I checked was 102 characters) from ezmlm-ndx, Yahoo, and Google mailing lists. Should this be enforced, ignored, reported?
