Just a guess, but it may not be sendmail per se. If there are issues
with the DNS, that could result in multiple long delays, giving the
half-hour time you're seeing for not all that many messages. Of
course sendmail may be throttled for some reason, or an upstream
gateway is throttling your host, or something.
