Narrowing sed Results in While Loop
Code:
find $SRC -type f -name *.emlx |
while read FILE
do
if :
then sed -n '/From/p' $FILE
fi
done > $DEST-output.txt

The loop above spits out a .txt file with several lines that look like this:

From: John Smith <jsmith@company.com>

How can I narrow that sed result to spit out the email only? Maybe the "From:" line but only include the data in between <> symbols containing @. I'm running these results into a ldapsearch query which is why I need the email only.

You may try following also for just email, if your file only contains email information
Code:
$ echo "From: John Smith <jsmith@company.com>" | sed 's/.*<\|>//g'
jsmith@company.com

Code:
$ echo "From: John Smith <jsmith@company.com>" | grep -Po '(?<=<).*(?=>)'
jsmith@company.com

Code:
$ echo "From: John Smith <jsmith@company.com>" | awk 'gsub(/.*<|>.*/,x)'
jsmith@company.com

--edit--

if your interest is searching line starting with stringFrom then following might be helpful
Code:
$ awk '/^From:/ && gsub(/.*<|>.*/,x)' file

Code:
$ sed -n '/^From/ s/.*<\|>//p' file

Something like this should work for both the angular bracket style (name surname <emailaddr> )and the direct type email addresses (emailaddr):
Code:
awk '/From:/{gsub(/[<>]/,x,$NF); print $NF}'

It is best to quote the wildcard name specification to avoid unwanted expansion. Also, you could probably use the -exec clause instead of a while loop, then you could also use the + operator for more efficient operation, e.g.:
Code:
find "$SRC" -type f -name '*.emlx' -exec awk '/From:/{gsub(/[<>]/,x,$NF); print $NF}' {} + > "$DEST-output.txt"

There's also mails having "From:" lines ending with <br/>, and HTML- headers replacing < with &lt; and > with &gt; ; some even put the username in parentheses AFTER the email - address - try this to capture all of those as well:
Code:
sed -n 's/&lt;/</;s/&gt;/>/;s/ *[(>].*$//;s/^From:.*[< ]//p' file

Hello,

Following may help too.

1st:
Code:
echo "From: John Smith <jsmith@company.com>" |  awk -F"[<>]"  '{print $2}'
jsmith@company.com

2nd:
Code:
echo "From: John Smith <jsmith@company.com>" | sed 's/\(.*: \)\(.*<\)\(.*\)\(>.*\)/\3/g'
jsmith@company.com


Thanks,
R. Singh

Well, how about these mail file lines:
Code:
From: root@xxxx.com (root)      
From: username &lt;username@xxxx.com&gt;<br/>
