[fetchmail]ESMTP SIZE should be switchable, fetchmail header counted

Hi

I suggest to make the use of ESMTP SIZE
switchable by some config option.
Not only do many poppers report false sizes
(as stated in driver.c), but also does
fetchmail itself not account for it's own added
Received header.

while most SMTP-servers take it easy,
by RFC1870 (ESMTP SIZE), 6.1:
 A server is permitted, but not required, to accept a message which
 is, in fact, larger than declared in the extended MAIL command

anyway I'm going to fix qmail-pop3d, which doesn't count
the added CR and an additional blank line at the end of the message.
(it should by RFC 1939, 11)


regards and thanks for keeping fetchmail best of breed
Klaus
