Thank you very much; the solution was not to define any virtual_alias_domains. What you say makes perfect sense, but what I was misled by is that the docs don't mention the possibility of using a virtual_alias_maps file without also setting virtual_alias_domains. Anyway, I hope that my question and your solution will help future similarly-afflicted users. Thanks again, Jan
