Vesta Control Panel - Forum

Hi.

We are new with Vesta, just installed a new server, we can send e-mail to any domain using roundcube.

The problem is we can´t send e-mail to GMAIL using any php script, we get this error:

host gmail-smtp-in.l.google.com [74.125.22.27]:
550 5.7.1 [CS] Spam Detected. Contact your service provider for support

IP is not blocked by Gmail, because e-mails from Roundcube are fine.

Any help will be appreciated.

Thanks.

Check your IP with mxtoolbox.com

Ip is clean

We reinstalled server with CentOS and Directadmin and all e-mails are coming out.

So we reinstalled again with CentOS and Vesta and again same problem.

This is very strange.

You can't send mail only to gmail or on different servers too?

Just Gmail

Here Gmail and Hotmail

My IP is 100% good in mxtoolbox.com

Gmail / hotmail don't like your IP or your mail.

You can try to contact with Google about this prob:

Solved!

soluction is disable ipv6...

CentOS:
http://www.unixmen.com/disable-ipv6-centos-7/

actually, right solution is to make a reverse DNS to your ipv6... not to disable ipv6... because, one day, everything will be switched to ipv6...
gmail rejected your emails because you don't have a reverse DNS for ipv6...

dpeca, absolutely right.

reverse DNS or disabling ipv6.
