sendmail snapshot 8.18.0.9

[Claus Aßmann]

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

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