If traffic load/link costs justify it, alternatives are to: - migrate to a more customizable mail service provider instead of the 'one-size fits all' connectivity-provider's MTA. Not (necessarily) an Exim issue. - run your own Exim MTA on the 'terrestrial' side of the internet so you have full control of rulesets, filtering, response messages. A dedicated leased/owned box with 'root' access, fixed-IP, PTR record, in a 'proper' data center is what you will need. Cheaper than your bar or gasoline bill, but only if you are an alcoholic with an SUV.... ;-) Bill -- ## 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/
