No, never. It would be too easy to send infected mail,
which is far worse than an oversized spam.
(but I believe Maia does it)
There are two kinds of size limits:
- $sa_mail_body_size_limit limits a mail size above which
SpamAssassin would not be called. The option is there for
two reasons: SA wants to have the whole message in memory,
and SA can be slow on large mail. Large spam is rare (but
exists), so benefits of skipping SA on large mail currently
outweight the risk.
- @message_size_limit_maps limits the size of the message, and
can reject/bounce/discard/pass such mail. The only reason for
existence of this option is to cater for pre-queue content
filtering setups (not recommended), and to offer per-recipient
size limits (hardly useful, once the message has already been
received).
