do not receive email after installing sieve

Hi I followed all the steps contained here:

Did all carefully, at theend of process cannot receive emails, I can send

The only difference I had with the settings was the first line:

when you state: Append “sieve” after ‘lmtp’ in protocols on the first line:

protocols = imap pop3 lmtp sieve

the difference was that i did not have lmtp on that line .

in rainloop: Filters
Can’t connect to server

this also i did to enble lmpt

edit /etc/dovecot/conf.d/20-lmtp.conf file to configure dovecot to enable the sieve plugin.

protocol lmtp {

Space separated list of plugins to load (default is global mail_plugins).

mail_plugins = $mail_plugins sieve
}

I have 50 emailaccounts norreceiveng email,please help
