To connect your inbox to HubSpot Sales, your email server must support IMAP (Internet Message Access Protocol) and SMTP (Simple Mail Transfer Protocol). Below you'll find the requirements for connecting your inbox using IMAP.

If your email server is not currently set up for IMAP, please work with your IT administrator to make sure your inbox is configured correctly.

Server requirements

When you send an email, HubSpot connects with your email server over SSL (Secure Sockets Layer), which is also known as TLS (Transport Layer Security). The IMAP port must be open to traffic and should connect via SSL/TLS. You can connect via port 143 with STARTTLS.  

Please note: to connect your outgoing server, your SMTP server must support TLS. If it's not set up to do so, then you won't be able to connect your inbox. TLS v1.0 and subsequent versions are supported. Some servers support SSL v3, but because this version is outdated and therefore insecure, it's not eligible for connection.

Configuration

Your email configuration can affect your abilitiy to connect your inbox via IMAP. If you have different usernames and passwords for your IMAP and SMTP servers, you will not be able to connect with IMAP, as this configuration is not supported at this time.

Security certificate

In the case that your SSL certificates are not signed by a Certificate Authority, there is an option to allow a non-secure certificate when initiating the connection. You'll need the appropriate username and password to access your server as well as the IMAP and SMTP server names. You can follow these instructions to obtain this information or work with your IT team to determine the correct login credentials to use. 

Whitelisting

Your IT team might only allow certain IP addresses to connect with your inbox. If this is the case, your IT team will need to whitelist the IP addresses HubSpot uses to connect your inbox. You can contact HubSpot Support to get these IP addresses. 

Because authentication methods, security settings, and available protocols can differ from one email server to another, it may be necessary to work with your IT team to confirm that your email server meets the above requirements.
