For better readability once more. Sorry for the first post which was a bit
confusing because of its format!
Hello list,
I have a question regarding the configuration of postscreen. In my
current master.cf file I have not allowed SASL authentication for SMTP:
*smtp inet n - y - - smtpd -o smtpd
I have two mail servers that use different content transfer encodings for the
same content. Based on the configuration, I can't work out why this is the case.
One account for each server is configured in Thunderbird and the emails are
created and sent via this account.
Old server configuration

Both postfix servers announce ‘250-8BITMIME’ support.
And no special rules have been defined for handling 8bit character encoding.
So that doesn't explain what is happening.
