I don't use Sendmail myself so I can't really comment on its configuration. However the issue looks like a typical mismatch of UIDs on the socket:


As per the link above you could try running 'chown mail' on the LDA. This will match the ID to the 'userdb' socket unix_listener (user = mail):

Good Luck
