I installed postfix on my Ubuntu server 11.04 (or is that 11.10?), so I could send mail using PHP. Everything works with GMail, Hotmail, etc, but Yahoo! mail users aren't getting any emails (even in thier spam folder). Same problem using the mail command on the server. If I use the mail command on my mac to Yahoo, it works fine.

Any idea where the problem is from, and how to fix it? Thanks in advance!

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

check /var/log/mail/error & your postfix queue.

Your emails to yahoo will be in the queue with the error/status codes returned from yahoo.

I have an issue were yahoo delays delivering email, due to 'users reporting it as spam'.
