dovecot SquirrelMail с sendmail в соединении Fedora [127.0.0.1] отказано при отправке

Мы используем Fedora 25 с sendmail-8.15.2-8.fc25.x86_64, и при отправке сообщений через SquirrelMail это занимает довольно много времени. Эти журналы появляются:

delay=00:00:15, xdelay=00:00:00, mailer=relay, pri=46987, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]

Я попытался это предложение:

# SMTP daemon options
O DaemonPortOptions=Family=inet, Name=MTA-v4, Port=smtp, Addr=XX.XX.XX.XX
O DaemonPortOptions=Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1
O DaemonPortOptions=Family=inet, Name=MSP-v4, Port=submission, M=Ea, Addr=127.0.0.1

И:

cat /etc/hosts.allow
ALL : 127.0.0.1

Firewalld тоже в порядке:

firewall-cmd --permanent --list-all
[...]
  services: samba imaps pop3s http ssh nfs samba-client smtp dhcpv6-client mysql cockpit https vnc-server postgresql ipp-client mdns ipp dns 

rich rules:
        rule family="ipv4" source address="218.65.30.108" reject
        rule family="ipv4" source address="72.9.101.182" reject

Есть что еще проверить? В конечном итоге почта ДЕЙСТВИТЕЛЬНО уходит. Занимает почти минуту.

Изменить: используя предложение здесь, Я, по крайней мере, мог получать почту. Теперь кажется, что SpamAssassin замедляет работу из-за Pyzor, являющегося виновником.
