SMTP Error (451): Failed to add recipient "email" (Temporary local problem - please try later).
Here are the steps to follow:
-
Run
/scripts/mailperm --force
, then run/scripts/updateuserdomains
. -
Optionally, you can run
/scripts/forcelocaldomain domain.com
(this will add the domain.com to the/etc/localdomains
file). -
Alternatively, manually add the domain to the
/etc/localdomains
file.
Note: Ensure that the domain is listed in the /etc/localdomains
file.
