This gives me the opportunity to plug a wonderful book: Michael W. Lucas recently published Networking for System Administrators. Check out the reviews -- none less than 5 stars.
You may recognize his name, as he's published a number of well recognized FreeBSD books, including Absolute FreeBSD, FreeBSD Mastery: Storage Essentials, and the very recently published FreeBSD Mastery: ZFS. With "N4SA" at hand, not only will you learn about tcpdump(8), but you'll learn a lot about the rest of network management, problem source identification, and how to speak to network engineers with their terminology.

Maybe. But I think you'd have better luck with tcpdump traces, which log to the microsecond. I can't recreate your problem, as I've never used FreeBSD, and haven't used sendmail in many years.
