I have a platform that sends faxes via Email. When the Email is generated, it puts the senders phone number in the "From:" part of the header. So it looks like this:

From: "800-555-1212"@foo.com

SpamFilter is getting the correct "Mail from" but is converting this address to "@foo.com" (no quotes however) and passing it on. It is stripping the quoted field. (and thus becoming a protocol violation for the downstream Mail Handlers......)

If you can either post here or email us mailto:support@logsat.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - support@logsat.com a full copy of such a header when the email is processed by SpamFilter and another of an email received without SpamFilter we'll take a look.

Wilson,

Can you please email them again? I went back in our emails but did not find any from you with the headers.

The problem is caused by the "From" missing the "<" and ">" brackets in the address. If the header was specified correctly as

Mail from:< mailto:"1-630-572-6357"@www.personalreachmanager.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - "1-630-572-6357"@ http://www.personalreachmanager.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - http://www.personalreachmanager.com >

it would be accepted. Instead it's interpreted it as:

Name: 1-630-572-6357

Email: @ http://www.personalreachmanager.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - http://www.personalreachmanager.com

I think that the RFC interpretation is as SpamFilter sees it. BUT... You are correct in that Netscape (and others, including ours) SMTP servers instead interpret it differently.

SO...

In a few days we'll release a new build with a fix to recognize that address format.
