MailScanner won't run ...

[Joolee]

It seems that you are running postfix configured with the
"enable_long_queue_ids" option, see:
http://www.postfix.org/postconf.5.html#enable_long_queue_ids

I think it would be best to make a note of this in the MailScanner Wiki to
disable the option. Enabling this option causes Postfix not to use unique
message ID's which can cause problems when using software like Baruwa or
Mailwatch.
