  On the contrary, the log IS informative!

	Yes, way back when I did the 2.99.10, I didn't handle signals
	properly on Linux (the new way of doing them).  The problem is
	since long gone -- and my ZMailer releases are now on number 2.99.15

        A copy of this material is also on:
                ftp://ftp.cse.psu.edu/pub/src/zmailer/current/
                ftp://ftp.cs.toronto.edu/pub/zmailer/
	(How automatic?)

	(Be warned that the 34Mbps PTAT-1 sea-cable connection in between
	 Pensauken, NJ, and NORDUnet is down AGAIN, and we are on a "slow"
	 2*2M link...  Hmm... 400 ms to MAE-E -- Earth-GeoStat-Earth is
	 circa 260 ms light-speed, which means round-trip of 500+ms.
	 That's odd, I didn't see any report that Cableship Soverign had
	 fixed it yet ???  Perhaps it is now on some other cable.)
