I glanced through the MT Support Forums and didn't see anything in regards to this, but I didn't have a whole lot of time to look.

Here's what's happening: Every couple weeks, I'll get a few comments that do this type of thing:

In the author field: "angelrrsmr@aol.comTo: angelrrsmr@aol.comFrom: angelrrsmr@aol.comSubject: kvlP(C87BA01E,author)ZOl"
In the e-mail address field: "angelrrsmr@aol.comTo: angelrrsmr@aol.comFrom: angelrrsmr@aol.comSubject:"
In the URL Field: "http:// angelrrsmr@aol.comFrom: angelrrsmr@aol.comSubject: aw(C87BA01E,url)OY4QK1FA2lmq5DIVMRq28RS0KB Ed WPJEfnH3l7M06xz9."
In the comment field: "body"

Herein lies the problem: When I get my e-mail notification for comments, I notice that the "To:" field not only has my e-mail address, but "angelrrsmr@aol.com". So I don't know what else they could be using this for, but I could see this getting exploited.

My comment notification e-mails come up looking like this:



Anybody else run into this? I've posted an entry on my blog as well.

Other than that it is a comment spam, I wonder how it can be exploited in other ways?

The comment notification email you received could only have been received by you. I don't think the codes can be exploited to send the same email to any arbitary person.

Even though the text portion after the "IP Address: 137.164.143.111" line in your notification email looks like an email, it is not a email by itself.

To be sure, can you check your mail logs to see if the email was sent to anyone else?
