Maybe if you restrict VERP'ing to personalised deliveries (in mm_cfg.py) and do not personalise mail for a list with problem subscriber addresses then the list's outgoing messages will not be VERP'ed and hence rejected. Pity to lose the benefits of personalization and VERP but it may the only solution if you cannot persuade the destination mail domain's postmaster to fix his MTA/Spam filter.

In their infinite wisdom, DirecWay/DirecPC appear to be using a program that
rejects VERP'd from addresses.
A VERP'ed address is just a valid mail alias @ a mail domain. It is either a bug or misconfiguration that causes refusal to accept a perfectly valid mail address as the envelope return path or in the From: header. From the non-VERP'ed message it looks as though the problem may be with something called MailShield ??maybe this being the Lyris spam filter product - all X,000 dollar license of it??.
The whole point of a VERP'ed return address is that, because it is just a valid email address, it only has to be 'understood' and 'decoded' by the originating system's MTA if it is returned. For all the MTAs between originator and recipient's MUA, the presence/absence of VERP'ing is irrelevant and not their concern.
What appears to be causing your problem is a badly implemented/configured spam filter which is applying an invalid policy to reject you messages; I suspect it may be some rule about the length of the mail alias in the return path or, heaven forfend, the From: header. The VERP'ed alias may be longer than some arbitrary limit being applied.

Is there anyway to disable VERP (which has proved very useful in handling
bounces) on a per recipient or per list basis????
