-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A client with a new iPhone (not sure what model), attempts to setup imap/smtp using starttls. As part of the setup, the iPhone apparently probes the smtp server on port 587 with an SSL handshake:

I don't think there is any mail server that will respond on port 587 to an unsolicited SSL handshake. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEARECAAYFAlW6hxAACgkQL6j7milTFsHkkACcCAD+0EV/nO1N5PSLZyI1uS8L lakAn3qLM8ZqAUTS/ZzHyR3lPbX3pKoA =hcQH -----END PGP SIGNATURE----- _______________________________________________ mailop mailing list mailop@mailop.org http://chilli.nosignal.org/mailman/listinfo/mailop
