they do. The problem lies entirely with *some* of the subscribing systems -
probably local mail exploders. Mailing-lists are useful because many people
only have access to email, not net-news etc, plus they are a good forum for
small focussed discussion. They've been around for over 15 years but are
still a problem to administer. These days CCmail/MicrosoftMail/MHS gateways
are frequent offenders in returning messages about local delivery problems
to all the subscribers of the mailing-list. The problem may lie with the
configuration of these gateways rather than the software itself, but the
vendors should make it harder to misconfigure them. Technically a lot of
problems with email systems come about from misunderstand of the difference
between the email envelope and the headers.
 
Actually in terms of receiving echoes to postings to the mailing-list, I
remember a system at ucsd being frequently involved at one point. I think
it was a bitnet machine, or at least likely to be a mainframe ibm cause the
hostname ended in "vm". Have other people noticed their echoes coming from
hosts like this? I guess I'll get a chance to find out when I hit the Send
button...
 
Perhaps people receiving messages in response to postings could forward
them to the list admin who could notify the sites causing the problem (I
seem to remember ucsd) and if they fail to make an attempt to fix it,
unsubscribe them as a last resort. Comments?

PS is anyone planning to setup an ftp site for confocal-related material.
We've got some primitive programs for
 1) transforming microVoxel and ThruView Plus animation files into
    QuickTime movies.
 2) transforming BioRad LUT files into a form usable by PhotoShop and NIH Image
    (these differ as to whether the RGB vaslues are interleaved). In general we
    recommend people apply LUTs and other image operations outside the BioRad
    system, but these converted LUTs have proved occasionally useful.
