Did you do any changes to your roundup installation?
This looks to me like you changed/added a detector that now throws an
AttributeError exception with the error message you've given.

For historical reasons, roundup treats AttributeError in a detector like
a Reject -- in the early days there was no separate Reject Exception in
detectors. (Richard: Maybe we should fix this, it's hard to debug detector
errors... and I don't think there are many old detectors out there now)

You might want to look around line 1387 of roundup/mailgw.py and print
out the full exception there to debug the problem. Please let us know if
the problem was in your own code or if it turns out to be a problem in
roundup core. In the latter case, please attach the full traceback.
You can print it by calling format_exc from the traceback module, e.g.
(completely untested):

at to of file:
from traceback import format_exc

around line 1387:
        except (TypeError, IndexError, ValueError, exceptions.Reject), message:
            exc = format_exc ()
            raise MailUsageError, _("""
There was a problem with the message you sent:
   %(message)s\n%(exc)s
""") % locals()
