Explanation of the error.
Your "tr" command strips out all line terminators (\n) for some unknown reason and converts them to "+" signs. My version of "sed" will not process lines without a line terminator, but yours appears to work (to my surprise).
The "bc" program fails because the input stream is not terminated with a linefeed character (\n).
When you "echo" the variable $var1 the "echo" statement appends a linefeed character (\n).
Btw. The unix standard version of "tr" will not translate three different characters into one. The length of the translate list must be the same both sides.
In your script this would only matter if there were carriage-return or form-feed characters in the line (which there are clearly not).

Whenever I send an email to my catchall alias via SSH (i.e., locally), Exim successfully pipes the e-mail to a PHP script, as I told it to do. However, when I try to send an e-mail to my catchall alias via my e-mail client (i.e., remotely), Exim won't pipe the e-mail. Any ideas?

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
