We are getting ready to deploy a postfix/dbmail/spamassassin mail solution for about 10,000 users. Close to 7,000 of those users are on a domain that is commonly (probably close to 50/50) referenced two different names, superlongdomainname.com and shortname.com. I plan on adding all user accounts as [EMAIL PROTECTED]
I can use postfix's canonical maps to change superlongdomain.com to shortname.com for mail delivery. I can also set up dbmail alias for each user. I can set up squirrel mail use either domain name. The problem comes with when users use pop3 or imap. Since we are an ISP, having our customers change their mail clients to only use shortname.com is a huge pain and next to impossible. If I set up all accounts under shortname.com, how do I make is so users can also authenticate when using superlongdomainmame.com? Any ideas or suggestions? Tom
