This is a historical glitch; I think Exim was doing IPv6 before the
standards came out. One change was made for 4.31:
8. The standard form for an IPv6 address literal was being rejected by address
parsing in, for example, MAIL and RCPT commands. An example of this kind of
address is [IPv6:2002:c1ed:8229:10:202:2dff:fe07:a42a]. Exim now accepts
this, as well as the form without the "IPv6" on the front (but only when
address literals are enabled, of course).
Looks like HELO/EHLO was overlooked at the time this was done.
