An address could, for example, be expressed as: zben%umd5%umd2@umda When umda gets it, it strips its name and changes the rightmost % to @: zben%umd5@umd2 Similarly, umd2 changes it to: zben@umd5 and I eventually get the message. Within the context of RFC822, a suggestion is to use the doublequoted string for this. Note that there is a thing in the sendmail configuration file that says "this is a final delivery". If set, then doublequotes are removed from the address before passing it to the server. Thus one could in some circumstances use something like: "zben@umd5"@umd2 although we do not support this at the present time. There seem to be both pro and con arguments on this, and I am going to let it ferment for awhile before I do anything with it... -- Ben Cranston ...{seismo!umcp-cs,ihnp4!rlgvax}!cvl!umd5!zben zben@umd2.ARPA
