Disable email for domain in Plesk Print

In Plesk v12 or newer, mail can be disabled on a per-domain basis via the Plesk interface.  Go to Mail tab -> Change Settings

 

For Plesk ≤11.5, mail service can be disabled for an entire subscription via Mail tab -> Change Settings -> uncheck "Activate mail service on domain", or for an individual domain via command line:

 

Linux (CentOS):

/usr/local/psa/bin/domain -u example.com -mail_service false

Windows:

"%plesk_bin%\mailmng.exe" --turn-off-domain --domain-name=example.com
