CAPI whitelist
Hi!
Multiple of our customers complained that an external resource (YouTrack) couldn't reach our SMTP server.
After hours of research we found out that the whole /16 supernet of IPs - that they are using a small portion of - are in the CAPI blocklist.
Before that, we tried whitelisting. We have a postoverflow whitelist that reads from a file. It's been working great.
It was after this that I found out about CAPI blocklists.
I have two questions, one out of curiosity, and one about the solution.
1. Why was it necessary to create a different whitelist for CAPI decisions?
2. Is it possible to point the capi whitelist to the same txt file we use for our other whitelist? (It is just a simple text file with IP addresses in CIDR format on separate lines.)
Thanks in advance!
