    ----

    It's time to `syspatch` your OpenBSD 6.5 or 6.6, for smtpd, on all supported architectures.

  7. La communauté “OpenBSD pour tous” annonce l’impérieuse nécessité de (sys)patcher OpenBSD !

    2 failles / OpenSMTPD

    blog.openbsd.fr.eu.org/index.p

    ----

    It's time to `syspatch` your OpenBSD 6.5 and 6.6, for OpenSMTPD, on amd64, arm64 and i386 architectures.

    For all others supported architectures, go to patch and recompil!

    openbsd.org/faq/faq10.html#Pat

    ----

    #OpenBSD #obsd4a #syspatch #OpenSMTPD #smtpd #smtpd_exec #smtpd_tls #amd64 #i386 #6.5 #6.6

  8. am I correct in thinking there isn't any change in #openbsd #smtpd smtpd.conf syntax in the 6.5->6.6 release cycle?

    (note: additions of new syntax doesn't count)
