Hi Aljoscha,

Note that you may need to upgrade to 6.3.13 if Gentoo backported the  
security fix from 6.3.12 to 6.3.11-r1; and you will have to configure the  
softbounce option properly. See the manual page for details.

If that does not help, please provide a full report as shown in  
<http://www.fetchmail.info/fetchmail-FAQ.html#G3>, notably the log is  
missing from your report.


Please also note that addresses with "-" as the first character are valid  
(see RFC 5321, RFC 5322), it's only a Postfix default setting that causes  
these addresses to be rejected (to protect the innocent on the assumption  
that many scripts will be foolish enough not to escape and quote things  
properly and miss the "--" argument separator).

HTH
