6 Mail::Alias - Maniulates mail alias files of various formats. Works on
7 files directly or loads files into memory and works on the buffer.
8
10 use Mail::Alias;
11
13 "Mail::Alias" can read various formats of mail alias. Once an object
14 has been created it can be used to expand aliases and output in another
15 format.
16
18 new () Alias objects can be created in two ways; With a format
19 specified- Mail::Alias::Sendmail->new([filename]) Without a format
20 specified- Mail::Alias->new([filename]}. Format defaults to SENDMAIL In
21 either case, the filename is optional and, if supplied, it will be read
22 in when the object is created. Available formats are Sendmail, Ucbmail,
23 and Binmail.
24
26 read () Reads an alias file of the specified format into memory.
27 Comments or blank lines are lost upon reading. Due to storage in a
28 hash, ordering of the alias lines is also lost.
29 write () The current set of aliases contained in the object memory are
30 written to a file using the current format. If a filehandle is passed,
31 data is written to the already opened file. If a filename is passed, it
32 is opened and the memory is written to the file. Note: if passing a
33 filename, include the mode (i.e. to write to a file named aliases pass
34 >aliases). Before writing, the alias lines are sorted alphabetically.
35 format () Set the current alias file format.
36 exists () Indicates the presence of the passed alias within the object
37 (if using memory access), or the current aliases file (if using direct
38 file access). For direct file access, the return value is the address
39 string for the alias.
40 expand () Expands the passed alias into a list of addresses. Expansion
41 properly handles :include: files, recursion, and continuation
42 lines.Only works when memory access is being used. If the alias is not
43 found in the object, you get back what you sent.
44 alias_file () Sets or gets the name of the current alias filename for
45 direct access.
46 append () *-Sendmail only-* Adds an alias to an existing Sendmail alias
47 file. The alias and addresses can be passed as two separate arguments
48 (alias, addresses) or as a single line of text (alias: addresses)
49 delete () *-Sendmail only-* Deletes the entry for an alias from the
50 current alias file.
51 update () *-Sendmail only-* Replaces the address string entry for an
52 alias in the current alias file.
53 usemem () Sets the working mode to use memory (indirect access). Use
54 read(), write() and format() methods.
55 usefile () Sets the working mode to use files (direct access). Use
56 append() and delete() methods.
