mutt_fqdn()

const char * mutt_fqdn	(	bool	may_hide_host,
		const struct ConfigSubset *	sub
	)

Get the Fully-Qualified Domain Name.

Parameters

may_hide_host	If true, hide the hostname (leaving just the domain)
sub	Config Subset

Return values

ptr	string pointer into Hostname
NULL	Error, e.g no Hostname

Warning

Do not free the returned pointer

Here is the caller graph for this function:

mutt_gen_msgid()

char * mutt_gen_msgid

(

void

)

Generate a random Message ID.

Return values

ptr	Message ID

The length of the message id is chosen such that it is maximal and fits in the recommended 78 character line length for the headers Message-ID:, References:, and In-Reply-To:, this leads to 62 available characters (excluding @ and >). Since we choose from 32 letters, we have 32^62 = 2^310 different message ids.

Examples:

Message-ID: <12345678901111111111222222222233333333334444444444@123456789011>
In-Reply-To: <12345678901111111111222222222233333333334444444444@123456789011>
References: <12345678901111111111222222222233333333334444444444@123456789011>

The distribution of the characters to left-of-@ and right-of-@ was arbitrary. The choice was made to put more into the left-id and shorten the right-id to slightly mimic a common length domain name.

Note

The caller should free the string

Here is the caller graph for this function:

mutt_lookup_mime_type()

enum ContentType mutt_lookup_mime_type	(	struct Body *	b,
		const char *	path
	)

Find the MIME type for an attachment.

Parameters

b	Email with attachment
path	Path to attachment

Return values

enum	ContentType, e.g. TYPE_IMAGE

Given a file at 'path', see if there is a registered MIME type. Returns the major MIME type, and copies the subtype to "d". First look in a system mime.types if we can find one, then look for ~/.mime.types. The longest match is used so that we can match 'ps.gz' when 'gz' also exists.
