Thanks, Jeroen, for your critique of my master.cf file. Per your suggestions, I'm removing the no_header_body_checks from my smtp configuration. I'm also moving the smtpd_recipient_restrictions into my main.cf, and making sure it's overridden as needed for all other parts of my master.cf file.
Doing this appears to have resolved my original problem with unwanted nulls in incoming mail. I know the real solution is for Google to clean up their mail system, but . . . . I'll also make it a project to clean up superfluous stuff in master.cf, though I plan to go slow and make sure I don't break anything. Thanks again. Rich Wales ri...@richw.org
