i have a forum which emails new members for confirmation codes, but i was testing it out and then i realized that the email is being sent to
yahoo bulk mail folders.

i went ahead and looked at all the headers and found.
X-YahooFilteredBulk

since i have a block of 8 IP's i went ahead and change my server so that the e-mail client on sendmail sends through a different IP address, and i verified it by sending some email to myself and checking the headers.

sure enough looks like my whole block is blocked and tagged as spam. i just got this server in march of this year and i have never used sendmail on it.

i went ahead and installed it so i could use the phpBB forum software, and this happens.

could anyone direct me to solution? is there a way to tell yahoo that i am a legit non-spammer?

much thanks

The exact criteria they use to inject the header aren't well-documented, so it's not possible for us to suggest a specific fix.

You can look into implementing domainkeys:

It's not trivial, and it's not entirely clear that it accomplishes your stated goal. Setting up a sendmail milter is not something many people can accomplish on their own. Even if you get it right, not every provider has adopted domainkeys, you'd probably need SPF records too.

is this the same thing to prevent the msn junk mail folder also?

SPF is, yes:

SPF is a lot easier for an individual webmaster to achieve than domainkeys. All you need to do is get a couple special txt records added to the zone file for your domain. Most hosting providers are getting hip to this and will play nice.
