Recently I was alerted byORBS.ORG that my site had been identified as being an email relay site, i.e. it could be used by spammers to relay messages to other sites. I plugged up all the holes, including an empty from address which ORBS.ORG tests for, since many spammers don't include a FROM address. However, an unexpected result of this was that I no longer could receive mail from the LISTSERV account. This is because it sends a blank address in the MAIL FROM: command in the SMTP protocol. I.e.: MAIL FROM:<> A real address is specified in the message header itself. I believe that more and more people are going to testing for this situation. Is there a way to correct LISTSERV to specify the address in the MAIL FROM: command also? Thanks. Mark
