"Self" sent spam problems

[Broadback]

I use SeaMonkey, which normally deals with spam emails well, once I have marked one as spam it remembers.
However recently I have been receiving emails, purportedly, from one of my email addresses to another. This SeaMonkey appears to have difficulty in dealing with, not a catastrophe but a pain the in derriere. Any suggestions please on how to deal with this? Thanks.
PS. I would like it bigger, but don't trust them!

You need Simon for this, BB, I've never used Sea Monkey in earnest.

This is known as from-spoofing. I'm not sure if there's anything you can really do in terms of filtering...

[Rik]

From spoofing. Sounds like an obscure event at the Winter Olympics.

not familiar with seamonkey either. Can you block your own email address on an inbound spamlist in seamonkey?

[Rik]

Simon uses it, So, he would be able to advise BB.

[Simon]

I might, but I would need to look at it, which I can't do from my phone.  Until later, all I can come up with is a junk filter, triggered by something in the header, but I'm not sure if this can be done.  I actually use Mail Washer, so I'm not all that well up on Sea Monkey's junk mail filtering, as I don't generally need to use it.

[Rik]

You were our last hope. 

[Simon]

I don't see that a 'From' filter need be a problem, as one is unlikely to send emails to one's self on a regular basis.

[Rik]

One concurs.

I do at times send emails to myself from one address to another when testing for something. However I have made sure that my email address is not in my address book as SeaMonkey would then not accept it a junk.

[Simon]

If you had a 'From' filter set up, and wanted to send yourself an email, would it not then just be a matter of retrieving the 'test' email from the junk folder?

[Broadback]

It would Simon, the only thing is that I have it set so that any email address to which I send and email automatically goes into my address book. All emails from any address in that book is not treated as spam. Anyway that is not my problem, I would just like it to set any email from that email address as spam. This is does not do, so I assume that it will not treat any email address set up in Account Settings as spam.

[Simon]

Do the 'spoof' emails contain the same message each time?  You can set up filters for 'If [Body] Contains...', if that's any use, otherwise, I don't think there's much else you can do, BB.

[Broadback]

Unfortunately not Simon, though thanks for the idea. Mostly the same subject, I'll just have to go on wondering if I could really grow bigger!

If you are on certain email lists the posts you send to the list come back from the list with the from address as your own.  In those circumstances you'd need a bit more in a filter than simply your own address.

Well, you could use a keyword from the Subject.  Have you thought about using Mailwasher?  It's free for a single mail account, but you have to pay for the Pro version to use it with multiple email accounts.

I know the domain mail handled by idnet and I imagine therefore idnet.net addresses have a "mail sent as myself" filter in the antispam component, maybe that would help?
