    Email flagged as spam

    This is a general query about email from Yahoo, Mail.com, site5 domains, etc., ending up in people's spam folders. (Eg, in Yahoo). Could this be caused by something specific to the home computer it's being sent from...? Seems to happen randomly, but quite frequently, and I'm not sure how to identify the cause. (All I can find is stuff to check whether certain mail servers are blacklisted, but that's not much help with something like a Yahoo email address.)

    (Thanks for the idea, but I'm wondering about personal/home email addresses...)

    blacklisting of the isp or the email address was previously known as a spammer

    One thing that helps when mailing either yahoo or gmail is setting up SPF records on your domain.
    Basically an SPF is a TXT record on your external domain dns that lists ip's allowed to send mail as this domain. When mail comes in and pass's spf its more likely not to get marked as spam (although not a guarantee)
