I agree with Philip. There are several sections of the Exim config which it is possible to remove and still have a fully functioning system. Consider ACLs - the documentation describes a complete ACL section which only has three lines (see Ch.40). It is possible to remove all the defaults and replace them with: acl_smtp_rcpt = do_not_use_this_acl begin acl do_not_use_this_acl: accept Success using that will depend on config in the routers, but it illustrates the idea. You could also completely remove the authenticators and rewrites, and all the routers except dnslookup, and all the transports except remote_smtp and *still* have a functioning system - crippled, but technically functioning. I can think of a number of situations where it's quite possible no retries at all would want to be done - think time-critical delivery such as for alarm systems (although using SMTP for alarm propagation is a bad idea, I know of several fire alarm systems that use it!). Perhaps the docs need to be amended to state categorically that: Removal (or omission) of the retry section, or inclusion of the section with no rules, results in there being no retry attempts on any sort of error condition. All errors will, therefore, immediately be treated as permanent. Graeme -- ## List details at http://www.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
