I started this thread in Sept and I'm just now digging into this again.
Some things I've done and also some I've found I need but not sure how
to accomplish. I've got a 'fetchmail.logrotate' file in
/etc/logrotate.d:

/home/chris/fetchmaillog {
        prerotate
        /usr/local/bin/fetchmail --quit
        endscript
	daily
	rotate 8
	compress
	dateext
	missingok
	notifempty
	create 0664 chris chris
	postrotate
	/usr/local/bin/fetchmail -v --nokeep --nosyslog --logfile
/home/chris/fetchmaillog --uidl -m procmail
	endscript
}

Running sudo logrotate -vd /etc/logrotate.conf shows me it reads the
fetchmail.logrotate file

rotating pattern: /home/chris/fetchmaillog  after 1 days (8 rotations)
empty log files are not rotated, old logs are removed
switching euid to 0 and egid to 104
considering log /home/chris/fetchmaillog
  log does not need rotating
switching euid to 0 and egid to 0

When the daily cron job for logrotate was run this morning I got this
output mailed to me:

/etc/cron.daily/logrotate:
error: fetchmail.logrotate:43 unknown option 'datext' -- ignoring line
fetchmail: WARNING: Running as root is discouraged.
fetchmail: no other fetchmail is running
fetchmail: WARNING: Running as root is discouraged.
fetchmail: no mailservers have been specified.
error: error running shared postrotate script for
'/home/chris/fetchmaillog '
run-parts: /etc/cron.daily/logrotate exited with return code 1

I've corrected the misspelling of 'dateext' however as can be seen it
tried to restart fetchmail as root. I've discovered that what I need is
a different state file for user chris

-s, --state <statefile>
    Tells logrotate to use an alternate state file. This is useful if
logrotate is being run as a different user for various sets of log
files. The default state file is /var/lib/logrotate.status. 

I imagine I need something like this which is in the /etc/cron.daily
folder

#!/bin/sh

# Clean non existent log file entries from status file
cd /var/lib/logrotate
test -e status || touch status
head -1 status > status.clean
sed 's/"//g' status | while read logfile date
do
    [ -e "$logfile" ] && echo "\"$logfile\" $date"
done >> status.clean
mv status.clean status

test -x /usr/sbin/logrotate || exit 0
/usr/sbin/logrotate /etc/logrotate.conf

So, can I modify the above and call it something else while changing
the first line to read something like

cd /home/chris/.logrotate

and the last line to be something like 

sudo -u chris /usr/sbin/logrotate /home/chris/.logrotate.conf

and put this

/home/chris/fetchmaillog {
        prerotate
        /usr/local/bin/fetchmail --quit
        endscript
	daily
	rotate 8
	compress
	dateext
	missingok
	notifempty
	create 0664 chris chris
	postrotate
	/usr/local/bin/fetchmail -v --nokeep --nosyslog --logfile
/home/chris/fetchmaillog --uidl -m procmail
	endscript
}

into the /home/chris/.logrotate.conf file?

Apologies for the lengthy post but I think I've covered everything I've
done so far and the results or lack there of.
