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.
