Hello! I'm running sendmail successfully, but occasionally some emails will not go through to some ISPs because they get marked as spam. My guess is it's because I have multiple domains hosted on the same server. So, the email would appear to come from domain1.com, but the return address is domain7.com. I've found yahoo, earthlink and comcast will deny those messages sometimes without specific user intervention. Is there a way with Masquerading that I can setup specific users for each specific domain? In other words domain 1: user1-1, user1-2, user1-3 (each receiving different mail) domain 2: user2-1, user2-2, user2-3 (each receiving different mail) In some ways it's like virtual hosting in apache...from the outside you can't really tell what server you're on/coming from with the various domains. I currently have some catch-all accounts, but would like to have more than one user be able to receive/send mail from a particular domain. Thanks!
