The delivery was disabled but shouldn't have been.

I am the list owner, but there have been at least 2 non-list owner
addresses that have also received this same message, when their
addresses shouldn't have been disabled.  Bounce processing was
enabled,  bounce_notify_owner_on_disable is yes.

Possibly, but it doesn't make any sense why our e-mail addresses are
bouncing when we are really receiving the e-mail that is sent out, so
I don't have much confidence that this will fix things.

Ok, apparently 1457 members out of 6327 are disabled, this number
seems quite high. 585 of them are gmail addresses, 602 of them are aol
addresses, which accounts for most of the disabled addresses. The rest
of them vary. Does that shed light on what might be happening?

By disabling bounce processing, will this  ignore the previous
disabling of addresses, since the recipients haven't received the
remaining 3 reminders (sounds like a tongue twister)?
