Thunderbird is a free, open source email, newsgroup, news feed and chat (XMPP, IRC, Twitter) client created by the Mozilla Foundation.

The vanilla version is not a personal information manager, although the Mozilla Lightning extension adds PIM functionality. Additional features, if desired, are often available thru other extensions. It supports UNIX mailbox format (mbox), Mork which is utilized for internal database and SQLite also used for internal database (since version 3). Files that bear the .p7s extension are email messages utilized in email managing programs for sending, receiving or just simply viewing protected emails encrypted with digital signatures.

These files contain information as well as the source of the email and whether the email has been edited or modified during transmission, which means users with these email management applications incorporated with P7S support can make sure that the emails they receive are genuine, are originating from trusted senders and are not tampered with, before they open and view the emails.
