Postfix IMAP/SMTP problem on Roundcube - (Ubuntu 18.04)
I installed postfix from this address for my server: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-on-ubuntu-18-04
I can send and receive mail with SSH. There is no problem in this part.
Then i installed the Roundcube. All settings look green on Roundcube Webmail Installer and i can see my email address and password, and the field I will enter.
My problem starts here.
I cannot login to this field with my information. (Failed to connect to IMAP server)
I also get an error when I enter this information on Roundcube Webmail Installer (Test SMTP config and Test IMAP config)
I made the settings like this;
SMTP Port: 25
IMAP Port: 143
Where am I making mistakes. Please help me.
