If you are using qmail, then tcpserver is part of it.

Usually tcpserver is running under supervise, so you must stop supervised qmail.

Er...i think NOT.

Susan, is qmail-send running? tcpserver is used to run qmail-smtpd to
accept emails but qmail-send does the actual queue processing and delivery.

Do you also use publicfile for serving webpages?

Susan, why do you say the email server is broken?

'tail -f /var/log/qmail/qmail-send/current'

That should indicate activity of qmail in processing and delivering email.
