Try putting the smtp machine name between square brackets:

define(`SMART_HOST', `[smtp.direct.ru]')dnl

there is something about the square brackets and its use to either use
or keep sendmail from using the MX or an A record instead for the listed
host (sorry, I can't remember the details, only that it works!).  I use
it (the square brackets) for my ISP's smtp server and I can send email
out through it.
