Mails

The Mails module implements a commandline email client. Emails can be written (via $EDITOR) and viewed, also in threads. Emails can be crawled for creating new contacts.

A Text User Interface is not planned, but might be there at some point.

The mail module implements a minimal Email client. It does not handle IMAP syncing or SMTP things, it is just a viewer for emails (a MUA).

The goal of the initial implementation is only a CLI, not a TUI like mutt offers, for example (but that might be implemented later). As this is an imag module, it also creates references to mails inside the imag store which can be used by other tools then (for example imag-link to link an entry with a mail - or the imag entry representing that mail).

So this module offers functionality to read (Maildir) mailboxes, search for and list mails and mail-threads and reply to mails (by spawning the $EDITOR).

Outgoing mails are pushed to a special directory and can later on be send via imag-mail which calls a MTA (for example msmtp) and also creates store entries for the outgoing mails.

CLI

The CLI of the imag-mail module is planned as follows:

• imag mail

  Requires configuration:

  • mail.outgoingbox
  • mail.accounts..maildirroot

  -A, --account - Specify the "account" to use for the opperation. A account is nothing more than a mapping of a name to a path where the Maildirs are located. It is specified in the imag configuration file. For example:

                    private -> ~/.mails/personal
  
                  If none is specified, the configuration is searched for a
                  "maildir" setting (where all Maildirs are found in). If
                  there is no such setting, imag-mail fails.
                  (or: read in documentation for --box).
  

  -B, --box - Specify a temporary location for a Maildir to work with.

• imag mail track [opts...] Track a new mail, mail file passed as path

  --refind - re-find messages. Loads all messages which are known to imag and compares identifiers, to update the imag-internal cache if a mail got moved

  -O, --output-id - print the store id for the new (or in case of --refind updated) imag entry

• imag mail scan [opts...] Scan a maildir and track all untracked mails

  --refind - re-find messages. Loads all messages which are known to imag and compares identifiers, to update the imag-internal cache if a mail got moved

  -O, --output-id - print the store id for the new (or in case of --refind updated) imag entry

• imag mail list <args...> List mails in a given mailbox for a given account or the default account

  -S, --style - print messages in a certain style Available: - 'linewise' - 'thread'

  -g, --grep - Filter by grepping for a pattern in body and subject

  -d, --daterange - Filter by date(range)

  -F, --filter - Filter by passed filter

    --thread    - Print only messages from the same thread as the found ones
  

  --format= - Format mails for showing. --format always colorizes output (specify color in config) except when using --no-pager or piping output.

                  When --tree is passed, the format is applied to the
                  fragment _after_ the tree graphic.
  
                  Default mode is 'default'.
  
                  Modes:
                    - 'subject': <Subject>
                    - 'simple': <From>: <Subject>
                    - 'default': <Date> - <From>: <Subject>
                    - 'fmt:<fmt>' format with passed format
  
                  Additional formats can be specified via the configuration
                  file. If a format has the same name as a predefined one,
                  the config overrides the predefined formats.
  

  --color - Colorize output (default). --no-color - Do never colorize output.

• imag mail show <args...> Show mail(s) - either in pager or by printing them to stdout.

  Mails are specified by message id or imag entry

  --refind - If a imag entry is passed but the mail file is not there, try to re-find it.

  --refind-in - Same as --refind, but a path to a Maildir or a tree of Maildirs might be passed to narrow down search space.

  -C, --concat - Open all mails in one pager (by concatenating them) instead of one pager per message.

  --pager - Use pager to show mails (default).

  --no-pager - Do not use pager to show mails.

  --multipager - Pass all mails as arguments to one pager call instead of calling the pager on each mail individually (default). Only possible with --pager.

  --no-multipager - Disable --multipager. Only possible with --pager.

  --format= - Format mails for showing. --format always colorizes emails (specify color in config) except when using --no-pager or piping output.

                  Modes:
                    - 'simple': Remove headers, except
                        From, To, Cc, Subject, Date,

                    - 'simple-imag': Same as 'simple' but also show imag
                      entry id.

                    - 'minimal': Remove headers, except From, To, Cc, Subject, Date,
                    - 'tiny': Remove headers, except From, To, Subject
                    - 'fmt:<fmt>' format with passed format
  
                  Additional formats can be specified via the configuration
                  file. If a format has the same name as a predefined one,
                  the config overrides the predefined formats.
  

  --no-format - Disable all formatting (same as --pretty=print and disabling color output).

  --color - Colorize output (default). --no-color - Do never colorize output.
