DigitalOcean's IP space blocked by Yahoo. Anyone know a good mail provider to send email (Not spam)? ( Cheap but reliable )

any suggestions for a ispconfig3 sstem with postfix and ubuntu? I did change 3 times the DO ip fort his and yahoo blocks again.

This happened to me, and I’ve already had set SPF/TXT record. The problem was that PTR records don’t match. To set PTR record just change your Droplet’s name to your server’s domain name. DigitalOcean will automatically set the value for the PTR record. That worked! You don’t have to use any other mail service (if you just want to send mail).

Gmail, Yahoo and many others uses your PTR record to double check that the sender’s servername (in this case, your server) matches the server’s IP.

I have decided to use mandrill and so far VERY pleased!

I managed to get php to also use mandrill by changing how sendmail works by installing msmtp.

Guide for others | centos 7

yum install epel-release
yum install msmtp

Created a new config file for it in /etc/msmtprc With the following info in the file:

account Test
tls on
tls_starttls on
tls_certcheck off
auth on
host smtp.mandrillapp.com
user MYUSERNAME
from noreply@mydomain.com
password MYPASSWORD
logfile /var/log/msmtp/msmtp.log

Then I modified the php.ini file. ( commenting out the old line for sendmail )

;sendmail_path = /usr/sbin/sendmail -t -i
sendmail_path = "/usr/bin/msmtp -C /etc/msmtprc -a Test -t -i"

Restarted apache and POW it works.
