Trouble sending from Mailman server to


I have a Mailman server with Dreamhost that is used for a discussion list to distribute information among about 50 members. My members with accounts have been reporting that they are receiving e-mail after a lengthy delay or not at all. I’m afraid that my Mailman server domain has been graylisted by Yahoo.

Is there a way to add domainkey identified mail header to a dreamhost subdomain?

Other ideas for how to solve this?

Thank you very much in advance for any ideas.


I have been experiencing the same thing. Any assistance from admins with this? Discussion list functionality was one of the reasons I moved my reg/hosting to Dreamhost.



Did either of you hear anything? We are generally having a difficult time sending to people with emails…
