Email sending fails with a "550 failed to meet SPF requirements" error-阿里云帮助中心

Problem description

When you send an email from Alibaba Mail, the delivery may fail. The bounce email contains a message similar to the following:

the mta server of * reply:550 failed to meet SPF requirements

Alternatively, the message may be similar to the following:

the mta server of 163.com - 163mx01.mxmail.netease.com(220.X.X.141) reply:550 MI:SPF mx14,QMCowECpA0qTiftVaeB3Cg-.872S2 1442548128 http://mail.163.com/help/help_spam_16.htm?ip=42.X.X.177&hostid=mx14&time=1442548128&nbsp;

Cause

This error occurs because the email fails the Sender Policy Framework (SPF) identity authentication check on the recipient's server.

Note

Sender Policy Framework (SPF) is a technology that authenticates an email sender's identity using an IP address. It is a highly effective solution against spam. The recipient's mail server checks the SPF record of the sender's domain to determine if the sender's IP address is listed in the record. If the IP address is listed, the server accepts the email. If not, the server considers the email forged and rejects it.

Solution

To resolve this issue, add a TXT record for your domain name. The default TXT record for Alibaba Mail is as follows:

v=spf1 include the following:spf.qiye.aliyun.com -all
