First, it appears that you have NOT disabled verify = sender (or one or more of its variations) entirely. ELSE not restarted Exim after editing the configure file. Second - the sender verification process can return more than a simple pass/fail. Well-covered in the docs, but not all in one place. You may be able to use sender verify to at least confirm that sending MTA's at-large exist and are configured to accept messages to (at least) 'postmaster'. You may need to either reduce failure to a 'warn', adding a header or score for later action, or stand ready to do a lot of whitelisting, as not all will verify a specific user. HTH, Bill Getting confirmation of specific 'other' user address validity is not all that common. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
