define Package/fdm/description
fdm is a simple, lightweight replacement for mail fetch, filter
and delivery programs such as fetchmail and procmail. It can
fetch using POP3 or IMAP (with SSL) or from stdin, and deliver
to a pipe, file, maildir, mbox or SMTP server, based on $(if $(CONFIG_FDM_WITH_PCRE),PCRE,POSIX regexp)

/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
The following encoding technique is taken from RFC 1521 by Borenstein
and Freed. It is reproduced here in a slightly edited form for
convenience.
A 65-character subset of US-ASCII is used, enabling 6 bits to be
represented per printable character. (The extra 65th character, "=",
is used to signify a special processing function.)
The encoding process represents 24-bit groups of input bits as output
strings of 4 encoded characters. Proceeding from left to right, a
24-bit input group is formed by concatenating 3 8-bit input groups.
These 24 bits are then treated as 4 concatenated 6-bit groups, each
of which is translated into a single digit in the base64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable
characters. The character referenced by the index is placed in the
output string.
Table 1: The Base64 Alphabet
Value Encoding Value Encoding Value Encoding Value Encoding
0 A 17 R 34 i 51 z
1 B 18 S 35 j 52 0
2 C 19 T 36 k 53 1

13 N 30 e 47 v

15 P 32 g 49 x
16 Q 33 h 50 y
Special processing is performed if fewer than 24 bits are available
at the end of the data being encoded. A full encoding quantum is
always completed at the end of a quantity. When fewer than 24 input
bits are available in an input group, zero bits are added (on the
right) to form an integral number of 6-bit groups. Padding at the
end of the data is performed using the '=' character.
Since all base64 input is an integral number of octets, only the
following cases can arise:
(1) the final quantum of encoding input is an integral
multiple of 24 bits; here, the final unit of encoded
output will be an integral multiple of 4 characters
with no "=" padding,
(2) the final quantum of encoding input is exactly 8 bits;
here, the final unit of encoded output will be two
characters followed by two "=" padding characters, or
(3) the final quantum of encoding input is exactly 16 bits;
here, the final unit of encoded output will be three
characters followed by one "=" padding character.
