sendmail doesn't read /etc/ssmtp/ssmtp.conf if called with -odb

[Kyler Laird]

I'm supporting an XEmacs/VM user. When he sends mail through VM, it calls "/usr/lib/sendmail -oi -oem -odb -t". This was failing in various ways so I finally traced it to see what was happening. I found that the -odb switch is causing ssmtp to ignore ssmtp.conf.

% strace -f /usr/lib/sendmail -t </tmp/letter 2>&1 | grep ssmtp ~
open("/etc/ssmtp/ssmtp.conf", O_RDONLY) = 3
open("/etc/ssmtp/revaliases", O_RDONLY) = 3
% strace -f /usr/lib/sendmail -odb -t </tmp/letter 2>&1 | grep ssmtp ~
open("/etc/ssmtp/revaliases", O_RDONLY) = 3
