I just tried to run the command that you have given.

Code:
cat filename | grep ^PenaltyError:= | cut -d '@' -f1 | cut -d ' ' -f8

It runs just fine without any problems. And so does

Code:
cat filename | grep ^PenaltyError:= | cut -d ' ' -f8 | cut -d '@' -f1

Output in both cases is : postmaster
I am using bash in RHEL 4.

Thanks,
Umar

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
