attaching a screenshot of MAIL LOG in Cyberpanel. using No SSL/TLS → send emails but does not receive.using SSL → shows misconfigured certificate (adding screenshot).Using TLS → shows misconfigured certificate (adding screenshot).when I use an SMTP plugin for wordpress, and use as host but still not working. I followed this ( Setup External SMTP on Google Cloud Platform (GCP)) to enable 2525 port.I tried to follow Mailsprings published workaround but with no success. Some googling has revealed that this a recurring issue. added DMARC, CNAME, SPF, MX records in 3rd party and used this tool ( ) to check records, all were coming good except smtp because it was using port 25 for testing. Gmail has stopped working in Mailspring yet again. Domain was from 3rd pary provider, so all DNS records were coming from there.since main domain was behind proxy, I did not put it behind.Sites had same email issue I did following to solve.Sites have same SSL issue, self-signed, invalid domain authority (solved it by putting behind cloudflare).I solved email issue temporarily by using GMAIL smtp.port 25 was blocked ( as I said in main thread title).sites were behind cloudflare SSL ( temporary solution for websites having above SSL issue).upgrading to CP 2.2 solved the issue in old Cpanel. They had SSL but it was self-signed, domain authority was invalid.My websites on old Cyberpanel did not have SSL I have now 2 setups of Cyperpanel on digital ocean.Īfter this much time I have some findings about my issues Sorry for reviving this topic but I am continuoulsy having issues with SSL, domains and emails. !(upload://zL7KvOROYit8v74deoF7FPXgOt3.png) so I need to solve this problem for ourselves. Is there any thing to solve my problem? I could use GMAIL smtp in my wordpress sites, but we are also using our email addresses for official communication also. I checked port 587 using telnet and its open, when I use port 25, it never shows any response except timed out error. I am not able to make POSTFIX to use 587 port or 465 (SSL) for mails. I added SSL to my email and it is showing no error except when i check it on, the domain name in SSL is ( I had this SSL issue in websites as well in last cyberpanel verison) so all my emails are connecting to :25 which results in connection time out. While debugging I found out that while sending emails, the Postfix is using port 25, which is disabled for outgoing by default in Digitalocean. whether I logged in to rainloop or connect my acocunt with SMTP on Mailspring/Thunderbird. however I am able to receive emails in my account. for about 1 month, I am not able to send emails through my websites. I am running a cyberpanel server on digital ocean with Ubuntu 20.04 LTS.
