Correction, .current_size is generated the user's home directory by the
"deliverquota" program that is also bundled with sam varschak's sqwebmail.
It is not associated with vdelivermail (vpopmail's vdelivermail) as I
earlier said. But an example of current user qutota usage is already
incorporated in vpopmail's vdelivermail.c. It calculates the mail size
before delivering a message to the user's Maildir. The part where it
calculates the mail could be used as an example in the new program that
would parse that information to STDOUT --> CGI --> custom html template code
---> user's custom webmail.
