SMTR-510 — Cannot force source address in SESSION-ACL
In the smtp-proxy, the source address is driven by SMTP-FORWARDER section, not by SESSION-ACL ones. The ACL selected for current session has SOURCE-ADDRESS set. This setting will be ignored.
If the SOURCE-ADDRESS was propagated from SYSTEM.ACL where it is set for other proxies, you can ignore this message. If the source address is to be manipulated, see smtp-proxy(5) manual page for instructions.
This message is a warning only.
