No, it would appear that it is in an error state, closing the
connection before receiving and acknowledging a QUIT command (required
by RFC 2821, section 22.214.171.124):

RFC 2821 requires that the sender (mailman) treat this as a temporary
failure of the "command or transaction". The receiving MTA may think
that the RCPT TO command has succeeded (in the sense of having sent a
valid response, even though it's a failure response), I guess, but
it's not obvious to me that Mailman necessarily gets the 550.
This is arguably a bug in Mailman (if it actually sees the 550
response), but it's definitely buggy and very error-prone behavior on
the part of the MTA. You might want to get one that's a little more
conformant with the spirit of the RFCs.

Deleting the .pck file should do the trick.
