Which IP addresses need access to my SMTP/IMAP server?

Most email server configurations will not need to care about IP addresses. However, if you are in a corporate/IT environment where you can only give specific IP addresses access to your SMTP/IMAP email servers, you can use the list below:

  • 52.27.236.234
  • 52.32.48.248
  • 54.71.177.103

These IP addresses may change in the future, without warning, so keep this in mind if your email syncing/sending stops working at a future date.
