[SM-PLUGINS] virtusertable plugin doesn't take proper e-mail address for composing emails

[Daniel B <db...@ed...>]

Hello,

I have seen that when I use the virtusertable plugin (based on the 
sendmail's /etc/mail/virtusertable information), I can properly login to 
squirrelmail with the full e-mail address, but when I want to compose a 
message and when I send it, then the received e-mail contains the unix name 
instead of the correct e-mail address (based on the virtusertable file 
also).

Hence if I login as jo...@my..., which is a unix account named 
'john-mydomain', then the sent e-mail will be coming from 
joh...@my... instead.
So virtusertable should also provide this inverted search in the 
virtusertable and send back the proper "From:" header in the e-mail so that 
the client can answer through the "reply" button properly.

I am using squirrelmail V 1.4.22-2 on CentOS 6.

Thank you.

Regards,
Daniel
