I’d changed the server name, when my ISP asked me to do so because the first time I configured it had an ‘_’ (underscore) character, which was not acceptable for the ISP once they upgraded their systems.
But now, still the old servername is reflected in the Message-ID’s generated by the Exchange server,like:
E09377E252CBD311B0B300805F3566C80B0A79@oiltools-server…
is the old one, this still appears.
It should have been
E09377E252CBD311B0B300805F3566C80B0A79@oiclmail…
with the new server name.
Any idea about this? Help appreciated.
