Also check your dns settings, check syslog for problems. And maybe try
disabling a blocklist or 2, might have one down.

Hi Rajesh,
Check you ClamAV logs to see if this is causing the error.
Verify you have the latest version of ClamAV as 0.975-1.4.1
had a bug when scanning.
best wishes

hi
for the last 10 days we are facing random errors
qmail-smtpd: qq soft reject (mail server temporarily rejected message (#4.3.0))
there is no load on the server and httpd for webmail, dovecot work normally.
no errors in clamd, spamassassin log files
even if i disable clamd and spamassassin the error still comes up.
error occurs in both smtp port and submission port (does not have spamassassin
scanning)
rebooting server resolves the issue for a 3-4 hours and then again the issue
starts.
tried repairing the queue using queue_repair.py -- some files are fixed however
issue is not solved.
/var/qmail/simscan folder contains around 50 files -- mostly all old dates.
memory limits are correctly set in smtp and submission run files
issue starts with a few rejects initially and then becomes continuous.
1) what could be the possible causes for this ?
2) can network connectivity issues cause this error ?
3) i am using seperate tcp.smtp cdb files files for port 25 and port 587 namely
tcp.smtp.cdb and tcp.smtp.587.cdb
how can i disable simscan for submission port by changing tcp.smtp.587 file
my current tcp.smtp.587 is as follows
:allow,BADMIMETYPE="",BADLOADERTYPE="M",CHKUSER_START="ALWAYS",CHKUSER_RCPT_FORMAT="0",CHKUSER_RCPT_MX="0",CHKUSER_SENDER_FORMAT="0",
CHKUSER_SENDER_MX="0",CHKUSER_RCPTLIMIT="150",CHKUSER_WRONGRCPTLIMIT="20",QMAILQUEUE="/var/qmail/bin/simscan",SENDER_NOCHECK="1",SPFBEHAVIOR="2",NOP0FCHECK="1"
thank you,
rajesh
