${ORANGE}DESCRIPTION${RESET}
|
|
When a default relay-host is configured (via ENV), the default behaviour
|
|
is to relay all your mail accounts outgoing mail through that service.
|
|
|
|
This command allows to opt-out from that default behaviour by excluding
|
|
all mail accounts belonging to a hosted domain you specify.
|
|
|
|
${ORANGE}EXAMPLES${RESET}
|
|
${LWHITE}./setup.sh relay exclude-domain example.com${RESET}
|
|
Any mail submitted from your '@example.com' accounts will be sent
|
|
without relaying through a default relay-host (if one was configured).
|
|
|
|
${ORANGE}EXIT STATUS${RESET}
|
|
Exit status is 0 if command was successful. If wrong arguments are provided
|
|
or arguments contain errors, the script will exit early with exit status 1.
