Query relay logs

Case-insensitive substring match on sender or recipient. The characters , ( ) " \ * and NUL each match any single character; every other character, including % and _, matches only itself. Trimmed; only the first 200 characters are used.

Only entries whose auth.from_domain (the visible From: header domain) equals this domain: case-insensitive and exact, so subdomains and parent domains do not match; an internationalized domain matches its xn-- form. Surrounding whitespace is ignored; an empty value is no filter. Entries whose auth or auth.from_domain is null never match. A value that is not a plain domain name such as example.com (no address, no trailing dot) answers 400.
