Hashcash Support

Hi,

I have been using swiftmailer for a while, and it is truly a great tool! However, some rather important emails - such as order confirmations - still get caught in spamfilters, despite following the tips given on the web site.

One way to reduce the probability of being flagged as spam is to include a hashcash stamp (http://www.hashcash.org). Basically, you spend a small amount of processing time to convince the mail server on the other side that you are not a spammer.

Since many server-side spam filters (esp SpamAssassin) now support hashcash out of the box (reducing your spam score), it would be great to have optional hashcash support integrated into swiftmailer.

Cheers,

Batrick
