Log Message:
mailsrvr: bound sockmimetext line scan with strnlen (CID 639931)

The inner while-loop walks (*np + len) up to RFC822_MAX_LINE_LEN bytes
relying on the embedded NUL test to stop early. When np points at the
"\r\n" literal used as the empty-body fallback (issue #822), Coverity
loses track of the literal's length and reports a 997-byte OVERRUN.
Compute the scan length up-front with strnlen so the bound is explicit;
behavior is unchanged but the OVERRUN false-positive is silenced.
