That rule would work properly when given a host.at address, wouldn't it? It's a rule like: R$*at$* $:$1@$2 that would mess things up. The dot just before the "at" wouldn't match the space in the first rewrite rule. -- Mike Pelletier - Usenet News Admin & Programmer "Wind, waves, etc. are breakdowns in the face of the commitment to getting from here to there.

Spaces are not technically part of addresses, so 'sendmail' never 'matches' a space. The space is treated only as a token separator in tokenizing an address, but is never incorporated into any of the tokens. Any address which is rewritten by: R$*at$* $:$1@$2 will be rewritten in exactly the same way by R$* at $* $:$1@$2 In fact both rewrite rules have the identical internal representation once 'sendmail.cf' has been read and converted to internal form. Just remove all such rules. They cause more problems than they solve, and today mail entering the internet with 'at' addresses is quite uncommon. You don't need those rules any more. -- =*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Neil W. Rickert, Computer Science <rickert@cs.niu.edu> Northern Illinois Univ.

I agree and if you want a reference to justify your decision for not supporting the 'at' addresses: In RFC 822, Appendix C. DIFFERENCES FROM RFC #733, C.5.5. AT-SIGN The string " at " no longer is used as an address delimiter. Only at-sign ("@") serves the function. This is dated August 13, 1982 - how long does it take to get this out of the sytem?
