Program Notes:
* Search all existing qpsmtpd logs for email to or from user@domain.tld:
* ''qploggrep'' cannot locate information that is not there. For example, since the ''dnsbl'' plugin drops the incoming connection before the remote server specifies the addressee, you cannot find any addressee information for messages blocked by ''dnsbl''.
qploggrep user@domain.tld
* ''qploggrep'' uses a case-insensitive search, so <tt>qploggrep abc</tt> will locate lines containing ''abc'', ''ABC'', ''aBc'', etc.
* ''qploggrep'' outputs the original TAI64N timestamp for each log entry. You can convert the result to human readable format by piping the results through ''tai64nlocal''
Examples:
* Search all existing qpsmtpd logs for email to or from user@domain.tld and convert the output timestamp from TAI64N to a human readable format:
qploggrep user@domain.tld |tai64nlocal
* Search for email to or from user@domain.tld that was denied by spamassassin:
* Search for email to or from user@domain.tld that was denied by spamassassin:
qploggrep spamassassin | grep user@domain.tld
qploggrep spamassassin | grep user@domain.tld
* Show all lines recording "connection x of y", sorted by the number of concurrent connections
* Show all lines recording "connection x of y", sorted by the number of concurrent connections

===Display messages that would have been blocked via DNSBL===
From time to time I try out new DNSBL services. Some of these generate instant comlaints from my users about correspondents who can no longer send us email.
This command has two objectives -
# Testing a new dnsbl service<br><nowiki>
Show you what emails would have been blocked by a new dnsbl service.</nowiki><br><nowiki>

# Review queued messages from servers that are now listed<br><nowiki>
Reviewing recently received emails that were queued by the mail server from hosts that are *now* listed on a dnsbl can be used to look for patterns that might help you tune your spam filter settings.</nowiki>

===List email disposition by TLD===
This command will look at your qpsmtpd log files for entries related to the TLD you enter, then tell you how those emails were handled. This can be useful to see how your server is processing emails with From or HELO fields using TLDs like ".faith", ".win", ".xyz", etc, which are being used by spammers to bypass some spamassassin tests.
This command requires [http://wiki.contribs.org/index.php?title=Email_Statistics#qploggrep qploggrep]
<nowiki>echo -n "TLD to review: "; read TLD; qploggrep $TLD\> |tai64nlocal |awk '{print $1 " " $2 "\t" $4 "\t" $5 "\t" $6 "\t" $7}'</nowiki>
===Count emails by TLD and disposition for today and yesterday===
This command will scan all qpsmtpd log files closed in the last day, pull out entries dated today or yesterday, then count the dispositions applied to each message by TLD (".com", ".org", etc):
Place the entire command below in your clipboard then paste it into command shell on your server. Adding "|sendmail -t emailuser@yourserver.tld" will email the report to the selected email address.
<nowiki>export LC_ALL=C; \
mydate=$(date "+%Y-%m-%d")\|$(date -d "yesterday" "+%Y-%m-%d"); \
cat -v $(find /var/log/qpsmtpd /var/log/sqpsmtpd/ -ctime -1 -type f -name "@*" -o -name current) \
|tai64nlocal |egrep $mydate | grep -v ^# | \
awk -v date="$mydate" -v tots=" {{Total}} " -F"[\t]" ' \
/logterse/ {split($4,ss,"."); ssn=0; for (i in ss) { ssn++}; \
sendtld=tolower( ss[ssn]); sub(">","",sendtld); \
tld=sprintf("%-20s",sendtld); plugin=sprintf("%-35s",$6); \
plugint=sprintf("%35s%-20s",$6" ","{Total}");\
countem=plugin tld; count[countem]++; count[plugint]++; count[tots]++; } \
END \
{ORS=""; print "Subject: Email Disposition on " date "\n\n\

================================= ==================== ======= =====\n"; \
for (j in count) { pct=sprintf("%2.1f",(count[j]/count[tots])*100); \
j ~ /Total/ ? myORS= " (" pct "%)\n": myORS="\n"; \
printf "%s%9s%s",j,count[j],myORS |"sort -b" } }'
