That bug is a bug in DTLS, which is quite different from regular
TLS, so it need not be the same issue.

Does this happen consistently, or intermittently?
Can you reproduce this with:
openssl s_client \
-cipher $(postconf -xh tls_export_cipher_list) \
-sslv2 \
-starttls smtp -connect mail.vex.net:25
Can you report the output of "openssl version -a"? And any
non-default postconf settings that tweak SSL protocol or cipher
selection.
If you capture a full packet dump and apply wireshark, it may shed
light on the handshake details. The client thinks the TLS finished
message has the wrong length, this feels like a problematic
interaction with TLSv1.2, but you're running 1.0.0x I think, which
has no TLSv1.2 support...
