All,
I hate to admit it, but this was actually something really simple.
I had the portion of the script that sent the e-mail in a separate file, that was (supposed to be) sourced at the top of the main script. When I was running the main script interactively from the command line (when everything worked) it worked because I had already manually sourced that other file earlier in the Terminal session. And when apache was calling that other file it didn't work because that file hadn't been sourced yet. The reason it showed up as a sendmail error message was because in that other file I had named the routine that sent the e-mail "SendMail" as opposed to "sendmail" but when that other file wasn't sourced it was calling the normal sendmail program with no parameters -- thus the error.
Multiple mistakes here: 1) naming the separate routine "SendMail" rather than something more unique, 2) not sourcing the other file at the top of the main file.

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
