Using Terminal and Find command.

find . -iname '*.jpg' -type f -exec rm -f {} \;

This command starts in the current directory, recursing through the entire subtree, looking for files only that end with ‘.jpg’. It will delete any such files.

find – the find program
. – search the subtree starting in the current directory
-iname ‘*.jpg’ – find all elements that match the shell pattern ‘*.jpg’. This should be done case-INsensitively
-type f – only match files
-exec rm -f {} \; – execute the command “rm -f {}” for each matched file, where ‘{}’ is replaced with the name of the matched file.

Also adding an -delete it should do the same.

find /yourdirectory -iname '*.jpg' -delete

Postfix Mail

This short guide shows how you can set up Postfix to relay emails through another mailserver. This can be useful if you run a Postfix mailserver in your local network and have a dynamic IP address because most dynamic IP addresses are blacklisted today. By relaying your emails through another mailserver that is hosted on a static IP address in a data center (e.g. your ISP’s mailserver) you can prevent your emails from being categorized as spam.

First step, you will need to make changes in your configuration file (in standard postfix configuration it would be /etc/postfix/main.cf). You need to add at the end of configuration file following lines:
