Get the combined ssl fingerprint:

openssl s_client -connect email.server.wan:993 -showcerts | openssl x509 -fingerprint -noout -md5

Example fetchmailrc:

set logfile /home/user/fetchmail.log
poll email.server.wan proto pop3
user "loginnamehere" password "passwordhere"
ssl
sslcertpath "/home/user/.fetchmail/ssl"
#sslcertck
nokeep
mda "/usr/bin/procmail -f %F -d %T";
sslfingerprint 'md5 thumbprint separated by :'s from first step'

The running script, print attachments with cups

#!/bin/bash
echo -n $(date +%m-%d-%Y_%H:%M:%S) ":>> " >> fetchmail.log
SUPPORTED_FILETYPES=.pdf.jpg
LP_OPTIONS="-d MFCL2710DN -o media=A4,tray1 -o fit-to-page -o position=top -o scaling=100"
FILENAME=$(date +%H%M%S).txt
/usr/bin/fetchmail --bsmtp ~/mailtemp/$FILENAME
if [ "$?" = "0" ]; then
/usr/bin/uudeview +e $SUPPORTED_FILETYPES -p ~/printable -i ~/mailtemp/$FILENAME
# rm ~/mailtemp/$FILENAME

for f in ~/printable/*

How to fix ssl certificate issue on fetchmail

Download the script:

sudo wget https://raw.githubusercontent.com/stevejenkins/unifi-linux-utils/master/unifi_ssl_import.sh -O /usr/local/bin/unifi_ssl_import.sh

Edit the variables in the script

Add your domain
UNIFI_HOSTNAME=unifi.yourdomain.com

Comment the three lines for Fedora/RedHat/Centos by placing a # for it:
# Uncomment following three lines for Fedora/RedHat/CentOS
#UNIFI_DIR=/opt/UniFi
#JAVA_DIR=${UNIFI_DIR}
#KEYSTORE=${UNIFI_DIR}/data/keystore

Uncomment the three lines for Debian/Ubuntu
# Uncomment following three lines for Debian/Ubuntu
UNIFI_DIR=/var/lib/unifi
JAVA_DIR=/usr/lib/unifi
KEYSTORE=${UNIFI_DIR}/keystore

Set the Let’s Encrypt mode to true:
If you only enable the line, by removing the #, you will get a loop ==Yes when running the script. So set it to true. Will still get some warning about missing [[:, but the doesn’t matter.
LE_MODE=true

You have built two or more network cards into one Linux system and each of these cards has its own default gateway. By default, you can only have one default gateway on a system. The case described would lead to asynchronous routing, whereby the router would reject the packets as appropriate.

The iproute2 program, which is included in all current Linux distributions and already installed even, as a rule, can be used for the solution of this problem. Normally, a Linux system only has one routing table, in which only one default gateway can make entries. With iproute2, you have the ability to setup an additional routing table, for one thing, and allow this table to be used by the system based on rules, for another.
