INHERITANCE

SYNOPSIS

15        my Mail::Message $msg = ...;
16        my $decoded = $msg->decoded;
17        my $encoded = $msg->encode(transfer => 'base64');

DESCRIPTION

20       Encode or decode message bodies with base64.  The e-mail protocol and
21       user agents can not handle binary data.  Therefore, binary data -but
22       even sometimes non-binary data- is encoded into ASCII, this is
23       transportable.
24
25       Base64 re-groups the bits of bytes, and maps them on characters. The
26       data contains bytes of 8 bits (an octet).  These are repacked into
27       groups of 6 bits, pointing in an array of characters containing
28       "[A-Za-z0-9+/]".  This way, three data bytes become 4 base64 bytes.
29       The encoded data will be trailed by '=' characters to align on four
30       bytes.

DIAGNOSTICS

120       Warning: Base64 line length not padded on 4.
121           While decoding base64 the data in a message body, a string was
122           found which was not padded into a multiple of four bytes.  This is
123           illegal, and therefore this data is ignored.
124
125       Error: Decoder for transfer encoding $type does not work: $@
126           Compiling the required transfer encoding resulted in errors, which
127           means that the decoder can not be used.
128
129       Warning: No decoder for transfer encoding $type.
130           A decoder for the specified type of transfer encoding is not
131           implemented.
132
133       Error: Package $package does not implement $method.
134           Fatal error: the specific package (or one of its superclasses) does
135           not implement this method where it should. This message means that
136           some other related classes do implement this method however the
137           class at hand does not.  Probably you should investigate this and
138           probably inform the author of the package.
