Hi,
This is just a pre-warning. I am in a process of implementing a
filter that would automatically unsubscribe email addresses that cause
permanent delivery errors, mostly user-unknown.
Addresses that return "host unknown" and similiar will be placed
into removal queue for 1 week from which they would be removed upon
successful delivery. Otherwise, if after 1 week the error does not go away,
the address will be unsubscribed.
Please send your comments about this proposal to alex@yuriev.com
Best wishes,
Alex
