I removed the certs for this and created certs for gulfbreeze.com, and the mail server, mail.gulfbreeze.com. There are other domains that have email on this server, like email@example.com. If I set up an outgoing email account, in Thunderbird, using firstname.lastname@example.org, server mail.gulfbreeze.com, port 587, user email@example.com, STARTTLS, I can send email from the mail server, no problem.
However, these settings do not work when trying to use this account to send mail in gmail. I used to be able to send fine, before changing the domain and cert. But now, if I use the exact same settings as I have in Thunderbird, gmail just says “Couldn’t reach server. Please double-check the server and port number.”
Once, it said the provider was taking too long. Every other time it says the server can’t be reached. I don’t know why this would work in Thunderbird but not in gmail.
My domain is: gulfbreeze.com
It produced this output:
“Couldn’t reach server. Please double-check the server and port number.”
