Troubleshooting

1. You're not fully authenticated
We were not able to check your DKIM signature

chmod 644 /www/server/dkim/domain.com/default.private
/etc/init.d/rspamd restart

Replace domain.com with your domain.

2. Your resverse DNS does not match with your sending domain

Be sure your reverse DNS matches with your hostname. Also, your MX mail server DNS should match with your hostname.

3. I can't receive an email.

Replace _dmarc value with v=spf1 a mx ip6:IPV6Address ip4:IPV4Address -all
Change the IPV6Address and IPV4Address with your server’s IPv6 and IPv4 respectively.

4. aaPanel does not use SSL itself.

Go to Settings - Toggle off Panel SSL and Toggle back on
