using ingo/procmail for setting vacation messages:
if a user enters text which contains line breaks (carriage return, newline
...(?)) e.g. to seperate the complimentary close from the text or
additional information .procmail then has each linebreak translated into
"\r\n", example:

----- entered into ingo form:
I am currently on vacation.
As soon as i return i will answer your mail personally.

With best regards

this leads to the following in the procmail script:
----- .procmailrc
echo "I am currently on vacation.\\r\\nAs soon as i return i will 
answer your mail personally.\\r\\n\\r\\nWith best regards\\r\\n   M. 
Krause" \

which is then display (e.g. in thunderbird) as one line:
-----
I am currently on vacation.\\r\\nAs soon as i return i will answer 
your mail personally.\\r\\n\\r\\nWith best regards\\r\\n   M. Krause

i think there is a command line option missing in the .procmailrc which is
created by ingo in the "vacation part" to tell "echo" to enable
interpretation of backslash escapes: -e
