My mail server easily gets the most phishing attempts from gmail. This is due to my unwillingness to blacklist Gmail. I report the abuse through there abuse page. The results in a slowdown while the abuser reformulates their sending process. I know this by watching the changes to the sending path in the header of the phishing attempts. The content and subject often don’t change but the header does.

I bet that if you were using gmail, those phishing mails would end up in your trash ... which raises the question: why does Google allow people who Google's own spam-filter can detect are sending 99% spam to keep sending e-mail?
