Some RE implementations are slow in certain locales.
Then it helps to switch to C locale:
In your case it can also help to switch from egrep to fgrep.
Further, your example exactly matches one field, then maybe this awk script is faster (an improvement of the previous post):
Hi All,

fdm
FDM(1) BSD General Commands Manual FDM(1)NAME
fdm -- fetch and deliver mail
SYNOPSIS
fdm [-hklmnqv] [-a account] [-D name= value] [-f conffile] [-u user] [-x account] [fetch | poll]
DESCRIPTION
The fdm program fetches mail from a POP3 or IMAP server or from stdin and delivers it based on a ruleset in the configuration file.
The options are as follows:
-a name
Process only the specified account. This option may appear multiple times. The account name may include shell glob characters to
match multiple accounts.
-D name=value
This option defines a macro for use when parsing the configuration file. The macro name must be prefixed with $ or % to specify a
string or numeric macro. This option may appear multiple times.
-f conffile
Specify the configuration file location. Default is ~/.fdm.conf, or /etc/fdm.conf if that doesn't exist.
-h Look at the HOME environment variable to ascertain the user's home directory.
-k Keep all mail after delivery, regardless of whether it matches a drop action. Note that mails kept in this way will be refetched by
fdm if it is run again on the same account.
-l Log using syslog(3) rather than to stderr.
-m Ignore the lock file and run regardless of other instances of fdm.
-n Do not process any accounts, just verify the configuration file syntax and exit.
-q Quiet mode. Only print errors.
-u user
Specify the default user for delivery. This overrides the default-user option in the configuration file.
-v Request verbose logging. This option may be specified multiple times. -vv will print information on configuration (useful with -n).
-vvvv duplicates all traffic to and from remote servers to stdout. This feature is disabled when using the -l flag.
-x name
Exclude the named account. Multiple -x options may be specified. As with -a, shell glob characters may be used.
fetch | poll | cache
The fetch command instructs fdm to fetch and deliver messages. The poll command polls the accounts in the configuration file and
reports a message count for each. cache allows fdm cache files to be manipulated: see the next section.
CACHE COMMANDS
The following cache manipulation commands are supported:
cache add path string
cache remove path string
Add or remove string as a key in the cache at path.
cache list [path]
List the number of keys in the specified cache, or if path is omitted, in all caches declared in the configuration file.
cache dump path
Dump the contents of the cache path to stdout. Each key is printed followed by a space and the timestamp as Unix time.
cache clear path
Delete all keys from the cache at path.
FILES
~/.fdm.conf
default fdm configuration file
/etc/fdm.conf
default system-wide configuration file
~/.fdm.lock
default lock file
/var/db/fdm.lock
lock file for root user
