Getting the below delivery failure message while trying to send emails to plesk server with drweb enabled.

[wpfmb type=’error’ theme=2]A message with the following attributes was not delivered because it contains an object which cannot be checked by antivirus.
Relaying such messages is blocked by administrator.[/wpfmb]

To resolve this error:

/etc/init.d/drwebd restart

If that doesn’t work kill all drweb process.

pgrep drwebd | xargs kill -9

Now check emails and if that start work try enabling dr web again by using:

/etc/init.d/drwebd restart
