Can anyone guide me in setting up a sendmail rule or configuration that sends numeric addresses like phone numbers to a particular user or process? I would like to have sendmail accept mail from a copier and route it to the fax send process if and only if the userid looks like a fax number. e.g. 6121231234 at faxserver.company.com It must be built off of the regexp map like this but I don't understand what to put in the last line to actually get it to deliver to someone else. #LOCAL_CONFIG Kallnumbers regex -a at MATCH ^[0-9]+$ LOCAL_RULESETS SLocal_check_mail # check address against\ various regex checks R$* $: $>Parse0 $>3 $1 R$+ < @ bigisp.com. >48 $: $(allnumbers $1 $) R at MATCH $#error $:553 Header Error But even if I figure that out, what am I supposed to put in an mc file (as opposed to the cf file) ? I'm running Redhat 9 and sendmail-8.12. Displaying my ignorance, Gerry -- Gerry Skerbitz gsker at comcast.net
