Help Please:

I have started receiving messages daily from some spammer using a Yahoo.com domain email address.

I added the senders to the Junk Senders list, however the next one that comes in has a different email address but in similar format to the previous messages. I want to create a rule filter, but not sure how to filter the message without blocking the entire @yahoo.com domain.

Here is the From line in the message header;
From: AAG Reverse Mortgage =?UTF-8?B?44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA?= AAG-Reverse-Mortgage-487030-aholu @ yahoo.com <taneshacarsen4554@yahoo.com>

Each time I receive a message, the email sender name is different, however the format you see above is the only similarity I can find, where there is a space between the sender name, the @ sign, and the sender domain. Most times there are also dashes as above but I am not sure if this is EVERY time. The only consistent format seems to be the spaces.

What do I need to do to build a rule that will check for these spaces so I can move it to the Spam folder? It would probably need to use a wildcard pattern to ignore the sender name and look more at the format.

I have attached a copy of the header from the messages I would like to filter.

I have been looking at the message headers to compare them and also compare a legit email from that domain but dont see any other data I could use to create a filter.

Any help is appreciated.

I have now started receiving basically the same spam, however now the headers are quite a bit smaller... here are 2 I received a short time ago. Does anyone see any detail I could use to create a rule?

Does anything in the return path match? such as the bolded part?
Return-Path: aagreversemortgage=?utf-8?b?44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca44ca?=aag-reverse-mortgage-487030-aholu@yahoo.com

or something in this from line?
From: AAG Reverse Mortgage =?UTF-8?B?44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA44CA?= AAG-Reverse-Mortgage-487030-aholu @

if there is something that always matches, you can use a words in the header rule to get it. If you aren't applying for a reverse mortgage, i would definitely create a words in the header rule looking for the words reverse mortgage or reverse-mortgage (use both words/phrases). It should be case insensitive so you only need a lower case entry for each. Of course, if you do apply for a reverse mortgage and the lender sends you info with reverse mortgage in the subject, it will be filtered. :)

Do all of the header have these lines with an outlook version in the 70's ? If so, add X-Mailer: Microsoft Office Outlook 7 to the words in the header rule. You can add one for each number except 1 - current versions are begin with 1.
X-Mailer: Microsoft Office Outlook 79.5
X-Mailer: Microsoft Office Outlook 77.4

Version 7 is non-existent, Outlook 97 was 8, current versions are 10 - 16 (going back to O'2003).

I will check the headers when I receive additional messages. I am sure I will probably receive a couple within the next few days.

I am still receiving the messages. The only common data I can determine is that they are using dashes in between the words for the spoofed email address, aside from what I mentioned above.
