change to smtp_psa stopped incoming mail

[coolemail]

I changed the max-load setting to 20 in /etc/xinetd.d/smtps_psa and /etc/xinetd.d/smtp_psa. I restarted xinetd and I think that emails are not getting in from remote now

The only change to /var/log/messages was a change from "smtp" to "submission":

Apr 9 11:56:14 plesk3 xinetd[32124]: START: smtp pid=28550
from=::ffff:74.125.82.43
Apr 9 11:56:14 plesk3 xinetd[32124]: EXIT: smtp status=0 pid=28547
duration=1(sec)


Apr 9 12:08:13 plesk3 xinetd[29107]: START: submission pid=1440
from=::ffff:84.45.196.145
Apr 9 12:08:16 plesk3 xinetd[29107]: EXIT: submission status=0 pid=1440
duration=3(sec)

Can someone tell me what I have done?
