    I use the smtp of the provider i host my domains with.. but Ive just read their FAQ and found this:

    Do you have an SMTP/Relay server?

    Yes, we supply an authenticated SMTP relay service using the same username and password that your pop account uses.

    We deliver the service on port 25 and port 2525 to allow for ISP's which block port 25 traffic.

    No, 'many' ISPs have an alternative port. Not all.

    On the topic of spam/ports etc... what's always baffled me is why someone hasn't come up with a solution to truly fight e-mail spam. As far as I know SSL certificates cannot easily be changed or copied and these work great for banking websites for example. Essentially an SSL type certificate for e-mail, again sent encrypted.

    It would theoretically be difficult for spammers to copy this, despite the fact they could successfully send an e-mail spoof. It would be near impossible to spoof an SSL certificate associated with an e-mail account and/or web domain.

    You may be thinking that you can setup a private key and a public key but this typically between specific users who may e-mail regularly. There isn't a global SSL type e-mail solution which works well for secure websites today.

    SPF, DomainKeys and so on are already in place to do this, but it's such a huuuuge change to co-ordinate it's still in the planning stages. Some ISPs are adopting it gradually, but even of those most are cautious about rejecting mail (as oppose to tagging it) because of how little mail can be classified in the first place.

    Chicken and egg problem, really.

    I don't see any mention of SMTP (or, as this is the Mail, 'e-mail') in that article.

    Absolutely you're right. And the chicken and the egg argument is an argument no one can win really; which I suppose is the state of play with regards to spam. I think you can reduce it but never remove it completely.

    Have a look at the discussion here. Disclosure - I have an interest in the "more elegant" solution discussed in the comments.
