Don't use that! It is way too fuzzy and error prone. At least it was
a long time ago on a Silicon Graphics Irix 5.x system.
One of our users had the habit to enter a "q" (for "quit") when he
had entered a recipient list in his interactive, text based, mail client.
The mail client took this "q" as recipient name and handed it over
to sendmail. Sendmail used the GECOS field to resolved this "q"
into a user name. The only match for "q" in the GECOS fields happend
to be the third initial of one of the other users. So that guy
received quite a few unintentional CC's of the first user's outbound
I would just put the alternative addresses in the aliases file.
