AW: [Mimedefang] Mimedefang crash (fwd)

Be careful with that Sun Blade 100.  It doesn't have much memory and it's
running on IDE.  That $950 is really meant to be a workstation.  I wouldn't
run any production mail server on IDE.  You might want to look at the Sun
Netra T1.

OK, I'll try to order a new Sun today to relocate my proxy server (a Blade
100 for $950 !), and I will run the multiplexor with the -l option to get
some extra info.

The extra load caused by the scanner is acceptable, and I think the
Kaspersky virus scanner isn't available for Sun+Solaris, is it?

Thanks for all the responses.

just get a few lines when the number of slaves changes (aditional slave
started or running slave killed because of timeout). if the settings for
minimal /maximal number of slaves is reasonable for your system this
shouldn't happen often.

will call the scanner once to check the whole message and if something is
found one again for each attachment. starting a virus scanner can be quite
an expensive operation.

something similar to mimedefang-multiplexor, only for virus scanning,
greatly increased the number of messages/second my server can handle.
