  • Same issue here..I spent weeks,thinking that was because of the free cp panels i have installed on my CentOS Amsterdam server i switched to Plesk cp panel and the same issue.I can send emails to gmail but not to yahoo. What could be the problem? Should i switch to another zone?

forgot to say that i have checked for blacklisted and came out what is the problem? is yahoo blocking it and if yes how can i fix this
I am also getting this... brand new server, IP not blacklisted, I am using SPF, and DKIM. No bulk emailing (in fact, it was only my own business email account on there). Yet Yahoo are blocking emails. I have many other non-Digital Ocean servers setup the same way (we use Virtualmin). So the only difference in this case is this server is Digital Ocean. So I am starting to wonder if Yahoo are blocking their IP's for some reason?
I could not wait the time it takes for Yahoo to unblock it (if they will) so I moved al the accounts on the server to a new Linode server I created, and the emails went right away.
I see, does anyone else has problems with sending mail to yahoo ? i do not want to move yet, its not a rush with the mail but i hope to get a fix
I'm having an issue where php can't send my contact form alert emails to any yahoo accounts for my clients.

They go to gmail without issue, but never hit yahoo, not even the spam folder.
@raymond: When you attempt to send an email to a Yahoo address, are you seeing any error output in /var/log/mail.log If you can post the output, we should be able to help you figure it out.

Same issue here.
I even filled out the form that yahoo suggests we fill in if we want to send email to their servers:

Aside from a standard response saying that they can’t guarantee delivery I didn’t get anything from them.

My error is this:

Same problem with Yahoo, mails just not getting through the recipient get an email from Yahoo saying Message not accepted for policy reasons, which ironically lands in the junk box! Here’s the log:[]:25, delay=561, delays=561/0.02/0.04/0.01, dsn=4.7.0, status=deferred (host[] said: 421 4.7.0 [TSS04] Messages from temporarily deferred due to user complaints -; see (in reply to MAIL FROM command))
