Best guess is that 38s includes 30s of "network issue" (probably dns)
delay time. Given that the Windows TB client doesn't appear to suffer
from the same problem - and assuming that it is configured to access
the same mail servers - that may help you isolate a network
configuration problem. A good place to start would be to compare the
DNS configuration in FreeBSD vs the Windows VM.
The "freezes" are a bit curious. If they're repeatable (i.e. occur in
response to a specific action) you could put TB into "offline" mode and
see if the freezes still occur. If they don't then they are probably
related to the same network issue.
