From: [EMAIL PROTECTED] <[EMAIL PROTECTED]>
The above is almost OK. The only error is not having doublequotes around the text part ([EMAIL PROTECTED]), which should be quoted because it has a @ in it. Other than that, having a @ in the text part is normal for Outlook and maybe others. Outlook insists on having a text part and if the person's name is not known it puts the email address in the text inside crazyquotes, e.g. From: "'[EMAIL PROTECTED]'" <[EMAIL PROTECTED]> Consider this: header CU_FROMVIAGRA From =~ /viagra/i It's very specific, isn't it? But it gets over 500 a day here, so we're using it.
Problem is that [EMAIL PROTECTED] is in a whitelist
As others said, this is bad. Spammers often put the recipient's domain in the sender address. Going by supposed sender address, the most commonly seen domain in spam is... our own domain. Probably you too. If you're getting a message from outside your system without any smtp auth, it does not deserve any negative points. It might even deserve a positive point, but we haven't done that yet. Joseph Brennan Lead Email Systems Engineer Columbia University Information Technology
