Anyone who knows anything about this? Is there a way to make the SMTP proxy not respond to EHLO, only HELO? I'm not an expert on these things but if the proxy responds to EHLO, shouldn't it also supoprt 8BITMIME?
I guess its off, because default configuration of Exim has the 8bit support off. And I read somewhere, that the AV engine could run into trouble when using 8bit mime support, but could be an old version of Kaspersky.
As long as you don't find an option in WebAdmin's SMTP-Config page,
you have to edit exim's config by yourself (which voids the Astaro Support)
-- This is not tested - I'm not even sure, if exim is compiled with the necessary options to support this --
# This would make exim advertise the 8BIT-MIME option. According to
# RFC1652, this means it will take an 8bit message, and ensure it gets
# delivered correctly. exim won't do this: it is entirely 8bit clean
# but won't do any conversion if the next hop isn't. Therefore, if you
# set this option you are asking exim to lie and not be RFC
# compliant. But some people want it.
