def handle(result, line, filename, lineNo): (source)

Parse a line from an aliases file.

Parameters
result:`dict` mapping `bytes` to `list` of `bytes`	A dictionary mapping username to aliases to which the results of parsing the line are added.
line:`bytes`	A line from an aliases file.
filename:`bytes`	The full or relative path to the aliases file.
lineNo:`int`	The position of the line within the aliases file.

def loadAliasFile(domains, filename=None, fp=None): (source)

Load a file containing email aliases.

Lines in the file should be formatted like so:

     username: alias1, alias2, ..., aliasN

Aliases beginning with a | will be treated as programs, will be run, and the message will be written to their stdin.

Aliases beginning with a : will be treated as a file containing additional aliases for the username.

Aliases beginning with a / will be treated as the full pathname to a file to which the message will be appended.

Aliases without a host part will be assumed to be addresses on localhost.

If a username is specified multiple times, the aliases for each are joined together as if they had all been on one line.

Lines beginning with a space or a tab are continuations of the previous line.

Lines beginning with a # are comments.

Parameters
domains:`dict` mapping `bytes` to `IDomain` provider	A mapping of domain name to domain object.
filename:`bytes` or `None`	The full or relative path to a file from which to load aliases. If omitted, the `fp` parameter must be specified.
fp:file-like object or `None`	The file from which to load aliases. If specified, the `filename` parameter is ignored.
Returns
`dict` mapping `bytes` to `AliasGroup`	A mapping from username to group of aliases.
