The difference is, that: 1. servers don't reject mail from:<u...@domain> where domain points to localhost, except where explicitly configures (e.g. badmx setting) 2. while sending mail to localhost does fail, the error message doesn't say what is the problem, is usually complains about mail routing loop. supporting "MX 0 ." (or anything agreed on and used) would clearly tell the sender where the problem lies. -- Matus UHLAR - fantomas, [email protected] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
