## Description

A GMimeMessage represents an rfc822 message.

## Functions

### g_mime_message_new ()

    GMimeMessage *
    g_mime_message_new (gboolean pretty_headers);

If `pretty_headers` is `TRUE`, then the standard rfc822 headers are initialized so as to put headers in a nice friendly order. This is strictly a cosmetic thing, so if you are unsure, it is safe to say no (`FALSE`).

#### Parameters

pretty_headers | make pretty headers |

#### Returns

an empty GMimeMessage object.

### g_mime_message_get_sender ()

    InternetAddressList *
    g_mime_message_get_sender (GMimeMessage *message);

Gets the parsed list of addresses in the Sender header.

#### Parameters

message | A GMimeMessage |

#### Returns

a GMimeObject containing the textual content that appears to be the main body of the message, or `NULL` if no body part has been set.

Note: This function is NOT guaranteed to always work as it makes some assumptions that are not necessarily true. It is recommended that you traverse the MIME structure yourself.

### g_mime_message_get_autocrypt_header ()

    GMimeAutocryptHeader *
    g_mime_message_get_autocrypt_header (GMimeMessage *message,
                                         GDateTime *now);

Creates a new GMimeAutocryptHeader based on the relevant Autocrypt header associated with the sender of an e-mail message.

If the message has no sender in the From: field, or has more than one sender, then this function will return `NULL`. Autocrypt should ignore the message entirely.

If there is one sender, but no single Autocrypt header is found that matches that e-mail address, a GMimeAutocryptHeader will be returned for the sender, but it will be incomplete (see g_mime_autocrypt_header_is_complete).

Note that the following types of Autocrypt headers will not be returned by this function:

- headers that do not match an address in "From:"

- unparseable headers

- headers with unknown critical attributes

- duplicate valid headers for the sender's address

The returned Autocrypt header will have its effective_date set to the earliest of either:

- the Date: header of the message or

- `now` (or the current time, if `now` is `NULL`)

#### Parameters

message | a GMimeMessage object. |
now | a GDateTime object, or `NULL`. | [nullable]

#### Returns

a new GMimeAutocryptHeader object, or `NULL` if the message should be ignored for purposes of Autocrypt.

### g_mime_message_get_autocrypt_gossip_headers_from_inner_part ()

    GMimeAutocryptHeaderList *
    g_mime_message_get_autocrypt_gossip_headers_from_inner_part
                                   (GMimeMessage *message,
                                    GDateTime *now,
                                    GMimeObject *inner_part);

Creates a new GMimeAutocryptHeaderList of relevant headers of the given type based on the recipient(s) of an e-mail message.

You must pass the decrypted inner part of the message to this function, since Autocrypt-Gossip headers are only stored within the encrypted layer.

If you don't already have the decrypted inner part available to you, you probably want to use g_mime_message_get_autocrypt_gossip_headers instead.

Each header in the returned list will:

- have a valid address

- be of the type requested

- be complete

If no Autocrypt header is found for a recipient, no GMimeAutocryptHeader will be in the list associated with that e-mail address.

Note that the following types of Autocrypt headers will not be returned by this function:

- headers of an unrequested type

- headers that do not match an address in "From:"

- unparseable headers

- headers with unknown critical attributes

- duplicate valid headers for a given address

On error (e.g. if this version of GMime cannot handle the requested Autocrypt type, or if a parameter is missing or malformed), returns `NULL`

The returned Autocrypt headers will have their effective_date set to the earliest of either:

- the Date: header of the message or

- `now` (or the current time, if `now` is `NULL`)

#### Parameters

message | a GMimeMessage object. |
now | a GDateTime object, or `NULL`. | [nullable]
inner_part | a GMimeObject which is the cleartext part of the inner message |

#### Returns

a new GMimeAutocryptHeaderList object, or `NULL` on error.

### g_mime_message_get_autocrypt_gossip_headers ()

    GMimeAutocryptHeaderList *
    g_mime_message_get_autocrypt_gossip_headers
                                   (GMimeMessage *message,
                                    GDateTime *now,
                                    GMimeDecryptFlags flags,
                                    const char *session_key,
                                    GError **err);

Creates a new GMimeAutocryptHeaderList of relevant headers of the given type based on the recipient(s) of an e-mail message.

Returns the same object as g_mime_message_get_autocrypt_gossip_headers_with_inner_part , but handles decryption and cleanup automatically.

`flags` and `session_key` are passed through to g_mime_multipart_encrypted_decrypt, as needed.

If the message is not actually an encrypted message, returns `NULL`: it should be ignored for purposes of evaluating gossip.

If decryption fails, returns `NULL`. In this case, an exception will be set on `err` to provide information about the decryption failure.

#### Parameters

message | a GMimeMessage object, which is expected to be encrypted. |
now | a GDateTime object, or `NULL`. | [nullable]
flags | a GMimeDecryptFlags, to be used during decryption |
session_key | session key to use or `NULL`. | [nullable]
err | a GError (can be `NULL`) |

#### Returns

a new GMimeAutocryptHeaderList object, or `NULL` on error.
