  • sendmail snapshot 8.18.0.9

    From Claus =?iso-8859-1?Q?A=DFmann?= @21:1/5 to All on Thu Jan 25 04:51:07 2024
    sendmail snapshot 8.18.0.9 is available for testing. It offers new srv_features options 'u2' and 'g2' which instruct the server to
    replace offending bare CR or bare LF with a space. This allows mails
    from broken clients instead of rejecting them, but without the risk
    of enabling "SMTP smuggling".

    SHA256 (sendmail.8.18.0.9.tar.gz) = 01a483f54479deef2ea8150ae8c10f126d639d1613bde73681fe0aafbe8e65d7

    is too lazy to trim his article, and it's wasting the time of all readers.

    That seems to fine, thanks!
    The logging entry "collect: connection from localhost" seems a little confusing ("localhost"). Maybe a bug?
