Configure Gptel, a simple and unintrusive LLM client for Emacs. EMACS-GPTEL-API-KEY is a list of program and arguments that are called by Emacs and that returns a string API key (safer defaults than having it as a string on-disk). By default, it tries to load the `emacs-gptel-api-key' from the password-store.

Maps keys randomly

Add default values to mail-providers-settings.

TLDR: Use 465 SMTP port, where possible.

Usually, the default SMTP port is 587, it supports both unencrypted and encrypted with starttls mode of operation. It potentially can be spuffed to established unencrypted connection, thus 465 is preffered by default as it always encrypted. If port 587 is needed it must be specified explicitly via port option or just by setting starttls option to #t.

Default IMAP port is 993 and it's encrypted by default.

If folder-mapping is not specified the generic-folder-mapping one is used.

Provide mail-accounts and mail-directory-fn for other mail-related features.

Return a list containing fqda and aliases combined together.

The tool for working with public-inbox archives and for applying patches (not only from public inbox). It has integration with notmuch and possibly a few other tools (get more info in the documentation of the project: https://docs.kyleam.com/piem/).

Return the value of user field or fqda if a value for user filed is not present.

Configure the Debbugs user interface for Emacs. Set the default packages to retrieve bugs for with DEFAULT-PACKAGES and the default severities with which bugs should be filered with DEFAULT-SEVERITIES.

Configure msmtp MTA.

TLS enabled by default, SMTPS 465 port is used by default.

It is possible to use SMTP+STARTTLS by setting starttls? to #t, but not recommended. For SMTP port 587 will used by default. https://serverfault.com/questions/523804/is-starttls-less-safe-than-tls-ssl

Also, port can be explicitly specified with port option (it's very unlikely you ever need this).

Configure smtpmail, a simple mail protocol for sending mail from Emacs. If no MAIL-ACC-ID is provided, no account-specific settings will be configured.

Configure l2md MDA.

Configure org-mime for wysiwyg html mime mail composition via Org Mode. You can change the exported HTML-ELEMENT-STYLES by providing an association list of ELEMENT . STYLE such as:

'(("pre" . "color: #E6E1Dc; background-color: #232323; padding: 0.5em;")
  ("blockquote" . "border-left: 2px solid gray; padding-left: 4px;"))

The above darkens exported code-blocks and adds a border and some padding to offset block quotes.

Configure notmuch and Emacs UI for it if emacs enabled. notmuch-queries is a list of pairs of query name and query, it added to notmuch config and can be used anywhere in search via query:query-name.

Configure email sending capabilities provided by message.el. mail-signature can be #t, #f, a string or a function, which accepts config with rde values and returns a string.
