doing BCC on procmail requires the envelope information
to be passed in by your MTA agen.
try the URL below:
http://www.ling.helsinki.fi/users/reriksso/procmail/mini-faq.html#bcc
and if your MTA is sendmail, read also
http://www.sendmail.org/faq/section3.html#3.29
Another problem on this solution is the amount of data going over the wire
for the case of :
to: user1(_at_)mydomain(_dot_)de
cc: user1(_at_)mydomain(_dot_)de
lets asume that there is a fileattachment of 10mb size !
When using the solution suggested at sendmail.org the mail is splittet into
2
at the ISP side so, there are 20mb going over the wire :|
IMHO a client side solution would be better...if possible :)
Any other ideas ?
