I understand that my question is not devoted very much to the problems of listserv etc. However, I was not able to find a reasonable explanation and I understand that there are many experts on this list: that is why I address my problem here: I have been receiving from time to time one-line empty message from myself dated January 1, 1970, 00:00:00. This week I received it every day and it makes me rather nervous. The sysop at our server does not clue what could cause this effect, he believes he lives with the gremlins in symbiosis. A colleague of mine met this problem several times as well. Any advice or help will be appreciated.
