aaP_marvin26camarillo It works for me. Can you try to wait longer? The code should be chmod 644 /www/server/dkim/xx.com/default.private systemctl restart rspamd Your code is wrong /etc/init.d/rspamd restart It should be systemctl restart rspamd
Mhdmd aaPanel_Kern No, there is no error. I am trying to send mails via a subdomain: "sub.domain.com" and I have set the mail domain as "mail.sub.domain.com". Is this wrong?
Mhdmd aaPanel_Kern No problem, but can I send mails from the subdomain while keeping the mail domain at mail.domain.com?
Mhdmd aaPanel_Kern But I have another question when using the SMTP server from an outside source like the WP Mail SMTP Plugin which always fails to send the Email on the first connection but works after. It seems like there is a timeout or some sort of threshold period in which you must continously send. Is there a solution for this?
aaPanel_Kern Hello, if the website program and mail service are on the same server, it is recommended to use the address: 127.0.0.1 25 port, and turn off SSL authentication. Mhdmd
aaPanel_Kern Hello, it is recommended that you check what is causing the problem first. You can test it on WP Mail SMTP, etc. Mhdmd
Mhdmd aaPanel_Kern Mailer: Other SMTP SMTP Error: Could not connect to SMTP host. STARTTLS command failed TLS not available due to local problem
aaPanel_Kern Mhdmd You can use this command to check whether the correct SSL is configured openssl s_client -connect mail.135mailtest.com:587 -starttls smtp or openssl s_client -connect mail.135mailtest.com:465 -starttls smtp If the display is not OK, please re-apply for SSL
Mhdmd SSL is valid, but the connection is always dropped the first time. Then it works. Then after some time of no use, the connection is dropped the first time then continues to work - repeat.
