There are two general classes of problems in using csh or a derivative as
your procmailrc's shell:
1. terminal-dependent commands in .cshrc that should be either placed in
.login or wrapped in an if structure that skips them if the shell is not
attached to a terminal;
2. csh's general problems as a scripting shell.
