Just feel free to adjust with some additionnal [A-Z] range or whatever but here is an idea :

(The trick is to add a space at the beginning of a line so that if the line contains only the mail address, the next regular expression used to reach the mail adresse preceeded by a space would also match.)

Code:
echo "Email address is abc.xyz@comp.com" | sed 's/.*/ &/;s/.* \([^ @]*@[^ @]*.com\).*/\1/'

(Just remember that if you want the hyphen to be taken as litteral in a list it should be set at the end of it

quick example : [:#@-]


also consider :
Code:
... | sed 's/.*/ &/;s/.* \([A-Za-z0-9.-]*@[A-Za-z0-9.-]*.com\).*/\1/'

but this would also match an adress with empty user and/or domain like : @.com

so you want it to be at least one char (and you don't want it to be a an hyphen or a dot you can for example:
Code:
... | sed 's/.*/ &/;s/.* \([A-Za-z0-9][A-Za-z0-9.-]*@[A-Za-z0-9][A-Za-z0-9.-]*.com\).*/\1/'

Just adjust it to your requirements

If you know that the mail address always appear at the end of line and after a space you can simply :

Code:
echo "Email address is abc.xyz@comp.com" | sed 's/.* //g'

Code:
# cat tst
first-name1.last-name@xyz.com
bla bla first-name2.last-name@xyz.com blebla blealdsfl
first-name3.last-name@xyz.com is a valid mail address.com
This line with valid adress.com: first-name4.last-name@xyz.com next nested address.com
last valid mail address.com first-name5.last-name@xyz.com
# sed 's/.*/ &/;s/.* \([^ @]*@[^ @]*.com\).*/\1/' tst
first-name1.last-name@xyz.com
first-name2.last-name@xyz.com
first-name3.last-name@xyz.com
first-name4.last-name@xyz.com
first-name5.last-name@xyz.com

(Ok i didn't handle the case where the separator is a tabulation instead of a space but it's easy to tweak the code or to tr -s '[:blank:]' ' ' <output before applying the sed statement

io::all::ftp

IO::All::FTP(3pm)					User Contributed Perl Documentation					 IO::All::FTP(3pm)

NAME

       IO::All::FTP - Extends IO::All to FTP URLs

SYNOPSIS

	   use IO::All;

	   "hello world
" > io('ftp://localhost/test/x');  # save to FTP
	   io('ftp//example.org/pub/xyz') > io('xyz');	    # GET to file

	   # two ways of getting a file with a password:
	   $content < io('ftp://me:secret@example.org/xyz');
	   $content < io('ftp://example.org/xyz')->user('me')->password('secret');

DESCRIPTION

       This module extends IO::All for dealing with FTP URLs.  Note that you don't need to use it explicitly, as it is autoloaded by IO::All
       whenever it sees something that looks like an FTP URL.

METHODS

       This is a subclass of IO::All::LWP. The only new method is "ftp", which can be used to create a blank IO::All::FTP object; or it can also
       take an FTP URL as a parameter. Note that in most cases it is simpler just to call io('ftp//example.com'), which calls the "ftp" method
       automatically.

OPERATOR OVERLOADING

       The same operators from IO::All may be used. < GETs an FTP URL; > PUTs to an FTP URL.

SEE ALSO

       IO::All::LWP, IO::All, LWP.
