Hello everyone,
Am I correct in understanding that the email server checks from which IP address a connection is established to send an email and by default, it verifies against the Spamhaus blacklist?
I'm asking because we want to send alarm and fault notifications via the Cloudron server from a regular DSL connection, and these addresses or address ranges often appear on blacklists due to dynamic IP addresses.
I'm concerned that important messages from the Cloudron server might be rejected as a result.
Thank you!
