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.
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.
Some servers support SSL v3 and/or TLS v1.0. Because these versions are outdated and therefore insecure, you won't be able to connect using them. Subsequent versions, however, are eligible to connect.
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.
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.
