Hi, is there any solution how to limit the use of Mail Forward just for specific user? The Mail Forward in my setup works fine, but I need to limit the use of mail forward address. Example: the address [email protected] is forwarded to [email protected], [email protected], etc... Only [email protected] should be allowed to send mail to [email protected]. Thanks...
I guess you could use a sieve rule for this. Code: require ["reject", "address"]; if not address :is "From" "[email protected]" { reject "Mail rejected - non-accepted sender."; } This is untested so you might need to read into the sieve docs
I guess Sieve is indeed the only way. But this also means you must remove the mail forward, replace it with a mailbox, and then add the forwards for the recipients in sieve plus the above filter as custom sieve rule in ISPConfig.
