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:

  • 52.11.177.187
  • 52.13.247.226
  • 52.27.236.234
  • 52.32.48.248
  • 54.71.177.103
  • 54.186.6.46
  • 54.200.191.154
  • 54.202.71.213
  • 54.214.129.39

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.
