There are so many reasons to get a bad IP reputation such as mail server behaviour is not satisfied, relays open to all and spamming too. In this case, it triggers the systems to get blacklisted when you trace the spam activities.

  • DNS record in Bad mode:
The server of the recipient checks the sender DNS record for security reasons. We are naming few DNS record for your references such as PTR, DKIM and SPF. If any mismatches exist then it fails to send the mail.

PTR:

It has a formal procedure to start server validation. For example, A server directs to IP address so that the reverse DNS will be the same. The spam mails will be sent from the mail server that is not up to the mark or virus-infected personal computer. Such an IP address won’t have a record called PTR.

DKIM:

To stop email spoofing, the better choice will be DKIM. DKIM helps to verify the valid sender domain by uploading the digital signature along with the domain name in the email. If the sender doesn’t have a proper DKIM record then it rejects the mail without hesitation.

SPF:

Again, to authenticate the sender activities SPF plays a major role. SPF has a set of IP address which sends the mail on the favour of domain. So, if you get an email from a sender it automatically checks the IP address from the maintained set only so, it permits sending mail to the recipient.

Solution: Choose an un-guessing name! It should be difficult for default entry to identify the name.

Errors in recipient:

There is more number of reasons behind recipient error such as filter configuration, blacklisting, disable or suspend mail account and improper entry or MX.

Solution: Check the MX entry using below command:

Code:
dig domain.com MX

Code:
telnet domain.com 25
