 Hi All,

and dspam antispam plugin 
 dovecot-antispam-plugin-43880985e3dd

and plugin configuration is given below:

protocol imap {
  mail_plugins = " antispam autocreate"
}
protocol pop3 {
  mail_plugins = antispam autocreate
}


plugin {
  antispam_allow_append_to_spam = YES
  antispam_backend = dspam
  antispam_crm_args = --config=/home/vmail
  antispam_dspam_args = --client;--user vmail
  antispam_dspam_binary = /usr/bin/dspam
  antispam_dspam_notspam = --class=innocent
