Argh! I checked the /home folder and it was indeed group and world writable. After
setting it to 0755 sendmail had no issues anymore. Sendmail checks permissions on
the entire path. I cannot remember setting it 0777, so something else must have set

Regarding the suid method: You mean method 1, 2 and 3 in the "Using Windows security
in Cygwin" article, right? I have nothing special set up, so it uses the default
method 1.

As to the sshd, I had it set up as a service already.

Thanks again for your help. I will announce the Sendmail release soon.
