Oh, wait. That depends who’s doing the rewriting. I understood The Doctor to be asking for help with a local configuration. All rewriting is done in the "rewrite" section, unless you’re doing something fancy with headers_add and headers_remove. If the problem is upstream, perhaps with the sending MUA or an intermediate server, then you can manipulate headers based on the authenticated_id, for example, and force them to the value that you want. On the other hand, you want to prevent rewriting *after* the email has left your server, there isn’t a general fix. You can’t make headers read-only, but it’s unusual for recipients change these headers, unless they’re mailing lists. I guess that, if you’re looking at an email that’s left your server, been rewritten by a mailing list, and then come back: then you could rewrite the header how you want it. But that won’t affect the copy that’s gone to third party recipients. -- Ian Eiloart Postmaster, University of Sussex +44 (0) 1273 87-3148 -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
