pessoal2004's post in Customer service replays - STMP was marked as the answer
Hi,
I found the solution.
On Customers / Customer Service I found the error "imap is not installed on this server".
To solve that I installed php-imap:
sudo yum install php-imap
sudo systemctl stop httpd
sudo systemctl start httpd
Then I found another error “[CLOSED] IMAP connection broken (server response)”
To solve that on “CUSTOMER SERVICE OPTIONS” / “IMAP options (/ssl): YES”
And now the IMAP is working.
