Per RFC 5321, sections 4.1.1.5 and 4.1.4, issuing an RSET command should not result in the HELO/EHLO domain being removed from the session. From section 4.1.1.5: > It is effectively equivalent to a NOOP (i.e., it has no > effect) if issued immediately after EHLO, before EHLO is > issued in the session, after an end of data indicator has > been sent and acknowledged, or immediately before a QUIT. And: > Since EHLO implies some additional processing and response by the > server, RSET will normally be more efficient than reissuing that > command, even though the formal semantics are the same.
Based on RFC 5321, section 4.1.4, any stored values should be reset if a HELO/EHLO command is sent subsequent to the original: > An EHLO command MAY be issued by a client later in the session. If > it is issued after the session begins and the EHLO command is > acceptable to the SMTP server, the SMTP server MUST clear all buffers > and reset the state exactly as if a RSET command had been issued. In > other words, the sequence of RSET followed immediately by EHLO is > redundant, but not harmful other than in the performance cost of > executing unnecessary commands.

The
HELO/EHLOdomain was being lost during anRSET. This fixes that.
