Our customers periodically ask us about the list of IP addresses of our servers to whitelist those IP addresses on their mail servers.
Because our cloud periodically change the number of application servers, it is not possible to give you fixed list of IP addresses valid for years.
To get the most up to date list of IP address execute following command in your shell:
dig _spf.ladesk.com txt
Result of such command could be following:
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6_6.1 <<>> _spf.ladesk.com txt ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52476 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;_spf.ladesk.com.

In the result you can see marked with bold 6 IP addresses of application servers used to access external services from our cloud (it includes Twilio calls, Facebook api, SMTP servers, POP3 servers, IMAP servers, API calls from plugins, etc.)
