Find your email server's IMAP and SMTP information

After that, you need to find the field for the Outgoing Mail Server. In the dropdown menu, select the SMTP server list. Another way of finding the SMTP port is given below.
Click on Preferences, then select Accounts.
Next, find the fields for the Outgoing and Incoming server. Here, the text box that you find towards the right is the port, and the longer text box is the server name. You need them when you set up your connected inbox in HubSpot.
Your IMAP and SMTP names are given below the server information.
