Postfix Incoming and Outgoing Mail Server Information

Hello everyone, I’ve just installed Sentora control panel and on the web interface, mail works perfectly. However, I have to add these mail accounts to my iPhone and I’m not sure which information I should write on the fields. I don’t know where Postfix installed but to access mail interface (roundcube), I use /etc/apps/webmail/. What should I write incoming mail host, outgoing mail host and outgoing mail port? Thanks.

Hello there,

As an Outgoing SMTP server, you can use the droplet’s IP address or the hostname of the server and use Port 587 or 465 as Outgoing SMTP Port

You can check our existing tutorial on How To Install and Configure Postfix on Ubuntu 20.04

I’ll usually recommend using mail services like Sendgrid instead of sending emails from your DigitalOcean droplet. You can also check our tutorial on Why You May Not Want To Run Your Own Mail Server

The mail host for incoming and outgoing mail should be your droplet’s hostname, the domain you configured your mail server with.

The ports should be 25 for unencrypted, 587 for encrypted on outgoing. Port 110 for incoming mail.
