Of course.

Actually I'd like an option for not verifying envelope-senders when being
invoked as rsmtp. A better alternative would be a list of additional
allowed characters for sender_address_local_part, as in helo_allow_chars.

I helped myself replacing the link of rsmtp with a script which mangles the
illegal characters to legal ones and calling exim -bS afterwards. This is
not the most elegant way to do it, but it seems to work.

The new rsmtp-script looks like:

sed "/^MAIL FROM:</y/;:/__/;s/^MAIL FROM_/MAIL FROM:/" | exim -bS

This effectively kills source-routing, but who uses it anyway.

Any perl-hacker there who can write the above line as oneliner to modify
just the localpart?
