Publisher review:Heirloom mailx (previously known as nail) is a mail user agent for Unix systems. Heirloom mailx (previously known as nail) is a mail user agent for Unix systems.
Features:
- Supports the MIME specifications. Mailx can send and receive attachments and code and decode international character strings. If the system libraries provide appropriate support, conversion between different character encodings is performed. In combination with a UTF-8 terminal, nearly all international languages are supported. External converter programs can be automatically invoked e. g. to view messages in HTML format.
- Supports IMAP. In combination with either OpenSSL or Mozilla NSS, IMAPS can also be used. With IMAP, folder hierarchies can be stored and managed on remote servers. This is particularly useful for people who use more than one computer to access their mail. Of course, it is also possible to use IMAP just for fetching mails and storing them locally.
- Supports caching and disconnected operation of IMAP folders. This speeds up operation while in online mode. It also makes it possible to transparently view and edit IMAP mailboxes without an active connection to the server.
- Supports POP3 to read messages on a remove server. In combination with OpenSSL or NSS, POP3S can also be used. Mailx can read and delete individual messages, thus POP3 accounts can almost be accessed like local mail folders.
- Supports SMTP to send messages directly to a remote server. A local sendmail interface setup is thus not necessary. In combination with OpenSSL or NSS, both the STARTTLS method and SMTPS can be used. SMTP AUTH is also supported.
- Supports S/MIME for signed and encrypted email (in combination with OpenSSL or NSS).
