Just mail, or overall total traffic?

If you can confirm that your MX is not having any local chokes in terms
of disk/CPU usage and you have spare smtpd listeners available, then
you may be running out of bandwidth. You could ask your ISP to
filter out a few common ports (135-139, 445) and see if traffic reduces.

If you could ask your foreign contacts to send you traceroutes, it might
be helpful in making a diagnosis.
