    Default Email spam

    I am getting a lot of Delivery Failed on emails I never sent and other PostMaster type emails.
    Only started happening in the last few weeks.

    I have chatted with my email provider twice now and had the SPF record adjusted and Spam Assassin increased and tweaked but these emails are still coming in and increasing.

    There is nothing on my machine of a malicious nature (first thing I checked) so my email is obviously spoofed. I thought the SPF record was meant to prevent spoofing....

    Anyway any idea what I can do to stop these?

    Use a professional spam blocking service, such as spamblocker

    You cannot get 100% of spam filtered/blocked (without blocking legit email) , so you need to be realistic about this .
    Its just life on the internet

    get a 'junk' 2nd email a/c : eg a gmail a/c .
    Use that email a/c to give to websites , services etc that really have no need for your email address

    The problem is this is a catchall email
    so doesn't matter what you put at the front it will get to me which means I cannot just use a different email because these are emails I have used before so were never "out in the world".

    I have the same problem. As fast as I delete them more keep arriving. I would liken it to swatting sand flies while on the Milford track.

    I have tried creating 'Rules' using the subject. Crafty buggers keep changing the subject and the language even and all messages have dodgy looking attachments. I thought about blocking the country of origin. I have the Junk Mail Option set at high but they still come through to my inbox.

    I might be wrong, but adjusting your spf wont have any effect on incoming spam ?

    No it doesn't
    But it is supposed to stop the spoofing of your email address, in theory.

    ?
    Do you really need catchall email ? No wonder you get so much spam.
    First step would be to use only use certain email adress, others (ie spam guesses) could then be rejected . Perhaps you can set that up in you spamfilter program or via you email hosting service .

    But if you want professional level spamfiltering, use a professional service . Its really that simple.

    only if your email hosting service or local spam filter supports it or uses it .
    From what I was told (by the professionals) its no longer of that much use, the spammers can get around it .

    Probably what is happening in this case. The service does use it but it does not seem all that effective.

    heres why

    http://baremetal.com/support/email_spf.html
    "......It is not very effective at blocking spam, as the spammers are better at working with SPF than most ISPs seem to be. They often buy their own domains and setup legit SPF records. However, it is quite effective at stopping spammers from forging mail with addresses inside of your domain. This is known as a joe job"

    Perhaps in your case, spf simply isnt being enforced , or not enforced correctly .
    How often do you hear of email being rejected due to no(or bad) spf record , it really doesnt seem to be enforced (in general) .

    See if your spamfilter has a greylisting option .
