I have set up Postfix on my CentOS server.
If the subject of the email contains some non-English characters (i.e.: accented letters), it gets ruined.
Here is an example.
this is a testà è ciao
Subject, once delivered to the server:
I know it is now an issue with MUAs because:
_ A lot of users have reported the issue - thus the MUA of the sender is out of the equation
_ I check the raw email on the server (I access the actual file with VI)
I guess it is a problem with charset, but I can't find anywhere in the Postfix config files how to handle the charset.
