Did that particular email (EB0C1E5B11) ever get delivered? If not, there
may be something within the email triggering lmtpd to crash. Are there any
binary headers or unusual content?
If the email is junk, there may be configuration options within postfix to
disallow such emails.
Attach a debugger to trouble shoot lmtpd. See the cyrus.conf and lmtpd
