I've not experienced any problems with my nucleus configuration. In my experience, the reverse lookup they provide for the IP address can be looked up to obtain the IP address again. That is, their lookup is consistent. I've not had any problems with email being rejected. In general, the "helo" greeting for SMTP is pretty much ignored by most servers as far as authentication/logging/etc. goes so it shouldn't cause too many problems if it mismatches. -- William Astle finger [EMAIL PROTECTED] for further information Geek Code V3.12: GCS/M/S d- s+:+ !a C++ UL++++$ P++ L+++ !E W++ !N w--- !O !M PS PE V-- Y+ PGP t+@ 5++ X !R tv+@ b+++@ !DI D?
