/var/log/maillog.0* or /var/log/maillog.1* if logrotate is running (which I assume it is)

Try this

Code:

# tail /var/log/maillog | grep "Oct  4"     <- two space between Oct and 4
# tail /var/log/maillog.1 | grep "Oct  4"   <- two space between Oct and 4

this will display logs of 4th Oct.

ok try grep command

Code:

# grep "Oct  4" /var/log/maillog

Did you try other file?
How many log files in log directory?

Code:

# ls -l /var/log/mail*

Are you able to view today's log?

There is possibility that your service not started on yesterday.

also post lines from below command

Code:

#tail -n5 /var/log/maillog
#tail -n5 /var/log/maillog.1

That it's important for you doesn't mean it is for anyone else. If you want help, have enough respect to ask decipherable questions; use words rather than text-speek.

Next, just how did the advice given by sem007 fail? Did it produce no output at all? Did it produce an error?

Rather than grepping the tail of the logs, try grepping the entire log file.

Hi mohdsuboor23,

You need to match the date with rotated maillog files.

Try this

Code:

# find /var/log -name "maillog*" | xargs grep "Oct  4"

Warm Regards,

Hi,

It entirly depends on your logrotation policy defined for the rotation of maillogs.

Read this log rotation guide

Also check the files /etc/logrotate.conf and any other logrotation configuration used for rotating maillog under /etc/logrotate.d/

Warm Regards,

I recommend using logwatch, it will compile the logs for the services you want it to summarized and mail them to you.
