It’s surprising to me in cyberpanel can receive mail but cannot send mail. Hesticap can send email but cannot receive email.
Without a domain I can’t really debug anything…
Thanks. Appreciate your help.
I have installed the full website again fresh. Maybe a few records left in Namecheap. If any other information needed please tell me. Got a sendgrid account. smtp relay may be possible.
