--- Comment #1 from Jeremy Harris <[email protected]> ---
1) Exim regards a bare LF in an SMTP command as a line terminator, equivalent
to a
   CRLF sequence.  This is for interoperability with badly-broken clients.
   Therefore the test sequence applied, 'RSET \n.,puul;?@' is taken as two
commands.

2) If EHLO had previously been used, pipelining is acceptable (by default;
modifiable
   by the configuration). The RSET command received is accepted.  The following
   garbled commend should be rejected.

3) If EHLO had not been used, pipelining is not acceptable. The presence of
further
   command characters after the received RSET is noted, and the RSET rejected
due to
   that.

This is not regarded as a bug.
