Postfix truncates EVERYTHING, especially when it is logged. The
intention is to protect your file system against logfile flooding
attack.

That seems absolutely reasonable from a tech point of view.
Unfortunately people have designed business processes based on
reports of mails from applications that send mails.
If this max_size_limit can be set to 100 chars then that should be enough.
Anyway these are app generated mails sending transaction receipt info
inside the Subject.
So there is no security issue of log flooding in this controlled
environment.
I wont mind a recompile of postfix.
I was also wondering ... If there a truncation of subject logging via
smtpd/cleanup too, Apparently there seems to be none.
