Thanks to the list for the help. I tracked this down to a mistake in main.cf with a too-restrictive smtpd_client_restrictions (I seem to have commented out the line that had permit_sasl_authenticated, which I think was a leftover elision from testing where I was trying to force the condition). Thanks for the clues. Intermittent failures are hard to debug. Best regards, A -- Andrew Sullivan a...@anvilwalrusden.com
