András,
Firstly, I cannot see this being relevant to anyone on the list.
It is - I see the warning attached to many people's mails (on this mailing list). Actually your mail has arrived with the warning: "This message may not have been sent by: errordeveloper@gmail.com - Learn more - Report phishing"
Secondly, from my personal experience SPF doesn't help very much - you will need DomainKey and that need to be setup in the MTA.
I'll need to see if SPF has a positive effect on this - at the moment, I just thought this is an emerging issue and people better hear about it from a mailing list than having person-to-person mails lost in nowhere.
My personal solution to all mail delivery issues is to use Google Apps with my domain name. If your SMTP server has potentially or really bad reputation (spam history, shared hosting, home ISP IP) - the chances that your mail arrives at gmail/hotmail/other are terribly unstable. I know this from my work experience at a shared hosting company.
The solution to this is to have private IP on a private host or use gmail/hotmail/other.
Yep, Google Apps mail has SPF (and maybe other things) built in, simple Gmail not.
