 a. The whm/cpanel server only uses the hosting server SMTP and does NOT use or use the smarthost relay configuration using Spamexperts etc., then simply run the update below:

# /scripts/upcp

b. Whm / cpanel server USES relay smarthost SMTP Spamexperts, then please go to WHM> Exim Configuration Manager> Advanced Configuration Manager and add the line below at the end of the @TRANSPORTSTART line / section

message_linelength_limit = 2048

Then save
