Fetchmail is a full-featured, robust, well-documented remote-mail retrieval and forwarding utility intended to be used over on-demand TCP/IP links (such as SLIP or PPP connections). It supports every remote-mail protocol now in use on the Internet: POP2, POP3, RPOP, APOP, KPOP, all flavors of IMAP, ETRN, and ODMR. It can even support IPv6 and IPSEC.


fetchmail --version --verbose
fetchmail --check --verbose
fetchmail --check


Change the port and use the keyword 'ssl'...

poll mail.domain.co.uk protocol pop3 port 995 localdomains domain.co.uk
     username "info@domain.co.uk" password "mypassword" is info here fetchall ssl

HOWTO: Stop Warning Message About SSL

To remove this warning message on every poll...

fetchmail: Warning: the connection is insecure, continuing anyways. (Better use --sslcertck!)

Add this line to your .fetchmailrc

defaults sslproto ''

HOWTO: Increase Message Size Limit

This sets the message size limit to 50MB. You have to edit 2 pieces of software. You also have to make sure that the Postfix limit is slightly larger than the Fetchmail limit :)


fetchmail --quit
sleep 3
fetchmail --limit 50000000


sudo postconf -e "message_size_limit = 51000000"
sudo service postfix restart

Date and Time Not Being Logged On Every Check

Add the preconnect command to the configuration file:-

preconnect "date >> /home/postman/fetchmail.log"
