Could not send email with Yahoo in contact us page

[TommyHara]

Hello,

I'm using vbulletin 4.2 and I tried send an email in my contact us page on forum (sendmessage.php)

But not success when I put email in Email Address is: mymail@yahoo.com

If I put email like : mymail@gmail.com or mymail@somedomain.com in Email Address field then everything's still ok. Mail will be received in my inbox.

Exclude, if I put yahoo mail then it didn't work

I moved forum to a new hosting, I think it causes by my hosting, right?

how to solve this?

Thanks in advanced!

Yahoo is normally pretty good about this. I have been dealing with this as well but with Microsoft mail.

If Yahoo has blocked your ip then you will need to either change it or see what they have for a resolution. Make sure your dns settings are correct though for mail. You mainly need an spf record and domain keys.

Let me know if you need help with this. I have spent the past 2 weeks getting both of my servers set and I have no trouble now sending mass email out to all email addresses.

Thanks Richie
But I don't think so


I'm using Directadmin for my vps

in DA, I setup email

email@mydomain.com -> mymail@gmail.com

in Admincp Forum

I setup email is: email@mydomain.com

and I tried to send from Gmail, Yahoo, Email Domain

Sent from Gmail, Yahoo, Email domain -> email@mydomain.com - OK

Sent from email@mydomain.com -> Gmail, Yahoo, Email domain - OK

everything is fine, email forward received.

But when send from contact us page (sendmessage.php) with input is mymail@yahoo.com then it returned error

Mail delivery failed: returning message to sender
and

This message was created automatically by mail delivery software.

I think that it's problem on forum code, not in DNS or Directamdin, right?

It looks like you are using google smtp from your server to send mail? Why don't you set up your domain smtp?

Also,check your site

I can see from the email header you need to have dmark--which is basically domain keys. What do you have set up in your email settings for smtp? Try turning off smtp.

2 days ago, I checked emails sent/received, they are good.
But today, I got error.
I don't use smtp in Admincp for sending email, still set the same as I did in the past.

I PMed you my domain
It has errors when I check http://mxtoolbox.com/

How to solve this?

If possible, PM me ways then!

Thank you
