I am new to setting up server, this is my first time setting up mail server on my own. I am using ubuntu with webmin, everytime I send and receive from gmail, I had no problem.
I can receive emails from yahoo but everytime I send emails to yahoo, the mail never gotten to the recipient. So yeah, I want to setup the SPF properly
My server's IP is 203.128.78.51
This is my current setup
v=spf1 a mx ip4:203.128.78.51 -all
In the Records list appears as:
domain.com. SPF 30 v=spf1 a mx ip4:203.128.78.51 -all
Is this correct?
I have already applied configuration and send more tests but still no success in sending mails to yahoo.
Any help will be greatly appreciated, thanks before
