[ale] odd error message

[kilpatms at gmail.com (Sean Kilpatrick)]

using Evolution for email.

Tried to send a message to stevew at twistnscoot.com,
but the message would not go out.

Error message:

"An error occurred during post-processing.  The reported error was
'Failed to apply outgoing filters.  RCPT TO <steve at twistnscoot> failed:
Bad chars in command.'"

Does anyone have a clue what might be going on here?
