Comment 1 for bug 1826534

Hi again,

the 500second threshold is probably only trigggered when the server greeting is replaced by stars, Which is still done (by default) by newer Cisco ASAs, that at least support ESMTP and in the case we ran into this also let the STARTTLS pass properly.

Combining PIXes which are not ESMTP ready, and DANE or other ways to enforce STARTTLS would be deadly for SMTP anyway. So leaving ESMTP activiated if STARTTLS is enforced would fix this in any case.

Kind regards,
    Lars
