Block all EMail TO a specified internal address

ChrisA_01
Hi guys, bit of an oddball request this but here goes.

I have a mailserver that accepts emails to "anything"@mydomain.co.uk and routes it into a single mailbox, when I register for certain online services I use an email address specific to the service I'm signing up for, i.e. "sophos@mydomain.co.uk" for this forum, that way if that email address leaks into spammers hands I can just block that address. I have just such a situation and have tried (and failed) to block the email.

I've tried using the expression filter but it's not what it's for and because the recipient address isn't contained within the EMail body it doesn't work. The default RBL picks up 99% of it but the occasional one makes it through. I can block this on my mailserver but I like a challange and I'd like to keep all anti-spam in one place.

Can anyone think of a way to achieve this?

Cheers

    Only healthy - we wouldn't be here if they weren't out to get us!  Actually, I also would have obfuscated the IP addresses. [:D]

    Funny, I think that worked in V4 and V5, but I haven't tried it in years.  In the header of the email you received, is the email address all in lower case?

    Cheers - Bob

    Lol, so would I were it not one of Microsoft's from Office 365.

    I checked the headers and it is in lower case. Not to worry.

    Really appreciate your time

    In a complete another environment I had a similar problem. The mail header was "missconfigured", there was no space between "To:" and my mail address.
    Depending on the filter module versions, the mails were catched or not...
