Dear List,
I have not seen on my INBOX/SPAM/JUNK folders at least 3 emails in the
last 10 days or so. It is hard to verify for me whether this is true so
from a system standpoint where do I start to check? I've grepped so far:
/var/log/qmail/clamd/*
/var/log/qmail/smtp/*
/var/log/qmail/spamd/*
and I have also checked the logs on the backup MX (that runs Postfix --
our main runs QMT).
Nothing seemed to indicate that the emails have been rejected.
Any pointers about what would be the best place to investigate would be
highly appreciated -- Sorry if this has been covered somewhere else, I
was not able to find it.
Thank you so much.
With Best Wishes,
Unai Rodriguez

qmlog is handy for viewing logs. I typically have a
# qmlog -f smtp
running, which shows every connection from outside servers.
The clamd and spamd logs will only show activity that gets past
spamdyke, which should be mostly what gets accepted. Relatively little
though compared to the smtp log.
If I want to verify that an account's receiving email, I usually send a
message from another account, preferably on a different server. You
might want to have a gmail or yahoo email account solely for this purpose.
If you have a situation where someone claims to have sent an email that
wasn't received (people do lie about that sometimes), inquire as to the
sender's email address, then
# qmlog -lc sen...@sentfrom.com
This will find them in all the logs. Keep in mind that on an extremely
busy server, you may only have a few days worth of activity.
FWIW, logging in QMT will be changing significantly in the future. I've
begun working on implementing an ELK (Elasticsearch, Logstash, Kibana)
stack with QMT. This will provide centralized logging for everything,
with powerful indexing, searching and analysis tools. Stay tuned for
this. :)
