Can I get a list of all IP addresses used by Missive's servers?

The servers Missive uses to connect to IMAP servers are hosted on Amazon Web Services (AWS). There are multiple IP addresses active at once and these may change several times a day.

If you need a list of IP address ranges to whitelist on your server, you can use the following file provided by AWS:

https://ip-ranges.amazonaws.com/ip-ranges.json

Although this may change in the future, all our servers currently originate from the US East 1 (N. Virginia) region, so you can filter the file and select only the IP ranges with "region": "us-east-1".

Note that this file may change regularly; you must synchronize the whitelist on your IMAP server accordingly. You can read more on the expected usage of this file.
