address alias file for mutt from command line

[zhang zhengquan <zhang.zhengquan@xxxxxxxxx>]

Dear mutt community:
Recently I found that
echo | mutt -s subjetc -a attachment recipient@host

extremely convenient to use especially if you have lots of attachments.

The only problem is that the recipient name is sometimes cumbersome to type.

I wonder if there is an alias file that I can edit for this purpose.

Thanks for any pointers,
Zhang
