Hello $name,

First of all, I'm sorry for the delay in getting back to you.

Last imapsync release is available from the page
http://imapsync.lamiral.info/paypal_return.shtml

You'll find in the attachment the invoice of imapsync 
software you bought and paid (dd/mm/yyyy $date).
The invoice file is named facture_imapsync-${invoice}.pdf
This invoice is in PDF format, ready to be print.

Should you need a hardcopy of this invoice, 
I'll send it to you upon request by regular mail.

As the law requires, this numeric invoice PDF file 
is signed with my private gpg key.

The resulting gpg signature is in the file named 
facture_imapsync-${invoice}.pdf.asc
you will also find in the attachment.

You can check I (Gilles LAMIRAL) really did generate 
this invoice with the following command line:

  gpg --verify facture_imapsync-${invoice}.pdf.asc facture_imapsync-${invoice}.pdf

or any other gpg graphical tool.

Once more, thank you for buying and using imapsync.

Any feedback is welcome.

Of course the verification doesn't prove anything until

- you met me,
- I agree that the fingerprint above is really mine
- I prove I'm Gilles LAMIRAL with an official paper.

Normally we won't have to verify anything unless 
I disagree with this invoice and the payment 
you made for imapsync.
