Cant use my hostname address to connect to smtp
« on: October 18, 2022, 07:00:02 AM »
This problem is rising reasonably quickly now when I set their emails with SSL using my hostname and they are getting errors. I always did this way for years and something I am a bit worried about. But if I set up SSL with mail.theirDomain.com then it works that is what I am currently doing now at this moment. this is the error that my clients are receiving.


Task 'info@theirDomain.com - Sending' reported error (0x800CCC1A) : 'Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.'


Thank you  :)

thankyou for your answer....

hmmmm
i dont know about your situation


but this is my step by step after i done install cwp from cli


login root, then i set the hostname ... example blabla.mydomain.tld
then i wait until the propagantion full and ssl are correct
at your case... is about email
then i got to email
then mail server manager
then set the hostname there (same with my cwp hostname ... subdomain not primary domain, never try use domain.tld )


after that everything is good. only need setup dkim spf etc




update: i never use mod or av at my cwp

update: try sent via webmail first....

what is weird is that if I create an SSL within the client side it works fine as I said in my main post. I don't really care so long I am getting an SSL I am good what I am afraid of is that this will start on everything that in involved with SSL emails

recheck mail server config on cwp
thenrebuild mail server with hostname


then re-check the SSL of your hostname (dont revoke too many times. if im not wrong.. LE limit issue SSL 3 time or 5 times only in 1 week)




"I create an SSL within the client side it works fine as I said in my main post."



sometimes this is happen to me. but... it fix automatically in few hours (crontab SSL run) still dont know why.
so ... yes i need more step to login to userpanel then issue it
or i just install zero-ssl for temporary from cwp to the client domain
