This is probably a bit off-topic but you may not have followed the
Postfix mailing lists. mailscanner uses *undocumented*
postfix-internal queue files which _may_ change between postfix
versions and which are NOT supported for use by outside programs.
People HAVE had problems with mailscanner and it is likely that these
problems are probably timing related and therefore more likely to
occur the busier the server. Postfix provides 2 STANDARD interfaces
for virus-scanners which are heavily used and efficient: SMTP/LMTP or
the "sendmail compatible" /usr/sbin/sendmail binary. Mail software
should only use those public interfaces which are guaranteed to
be supported, to be stable to and to work.
I don't share your negative view of Wietse.
In any case should you want to respond perhaps it's better we take
this off-list. I'm not that bothered either way.
The point I was trying to make is that using Postfix with Mailscanner
*may* lead to issues and if so will not get support from the postfix
users. The original poster should be aware of this. He is having
problems using Postfix with an unsupported virus scanner and should be
aware of this. [Using other virus scanners which do follow the
supported interfaces does not have this problem.]
