Mailnag is an application that notifies you about new emails you receive via the new GNOME 3 notifications system. It works with both POP3 and IMAP servers (and yes, it works with Gmail too) and looks pretty much like Popper (it's actually a Popper fork).
Since our last Mailnag post, the application reached version 0.1, getting some new features such as: automatic import of Evolution mail accounts on startup, you can execute a script on events such as "On mail check" or "On mail arrival" as well as new translations and bug fixes.
Also, Mailnag moved to Github, trying to make it easier for people to contribute so if you can help, visit the Mailnag Github page and help Patrick!
Firstly, let's install the dependencies (don't worry, you don't have to compile Mailnag) - these are most probably already installed, but just in case:
sudo apt-get install python-xdg python-notify python-gnomekeyring python-httplib2 python-gtk2 python-gobject alsa-utils gir1.2-notify-0.7
sudo yum install pyxdg notify-python gnome-python2-gnomekeyring python-httplib2 pygtk2 pygobject2 alsa-utils
Then, simply download Mailnag, extract it in your home folder and to run it, double click the "mailnag_config" file inside the mailnag folder.
Using Mailnag with Gmail
To use Mailnag with Gmail, on the Accounts tab click "Add", enter your Gmail email address and password, use "imap.gmail.com" under "server" (no need to enter a port) and check the "IMAP" box:
In newer Mailnag versions, also make sure the “Enable SSL Encryption” box is checked under your account settings.
Thanks to Patrick (zulu) for the tip!
