How to Install Thunderbird on Ubuntu 20.04


Thunderbird is a Mozilla-based new, lightweight mail, and RSS client. It works with a variety of email accounts such as POP, IMAP, and Gmail. It also has an integrated learning Spam filter which allows for easy mail organization through virtual folders and tags. Extensions can also be installed to add more features.

Thunderbird reigns supreme. It is completely compatible with your corporate customers who use Outlook on Exchange server, as it includes built-in support for Outlook calendar or meeting invites. It is quick, lightweight, and is perfect for SSL IMAP.

If you’ve ever used Outlook, Thunderbird will feel incredibly familiar. There are no hidden ribbon menus like in Outlook. For preference settings, everything is in a classic layout, and the message view is very compact. It is a classic technique which Linux users should appreciate. Thunderbird has a separate inbox for each email account. This is a feature that most of the Ubuntu users would like to have. Many users disagree while preferring to combine work and personal emails in a single inbox, such as Outlook 365.

For the longest time, the Windows Outlook client had a self-imposed default 2GB limit on IMAP inboxes. Pretty annoying, since your 64-bit OS can handle bigger. The funny thing is when it hit the limit, it wouldn’t warn you. It would simply stop receiving new emails.
