Aaaargh! Guest email rejections 520 (>20%) vs Members just 7. Further Guest launch emails postponed. Click on News item to read more

A further 70 came through on 23 November

I can’t resolve these by personal contact as with members, so will have to delete all the individual records which will take an age. Admin is not my favourite pastime! Please help by keeping your profile up to date.

Reading through the reasons for rejection they included

– blocked which means you or your service provider has spammed or blacklisted the Society. In these circumstances I will try sending you an individual email.  If that bounces my technical helper will research the cause.  If nothing we can do will have to delete your record.
– delivery temporarily suspended-

These two mean to me that a specific action by a Guest can be undone.  I will delete these last

But the rest of them are irrecoverable

– user does not exist
– user unknown
– cannot be delivered. This mailbox is disabled
– recipient rejected
– requested mail action aborted, mailbox not found
– bad destination email address ‘reject’
–  requested mail action aborted, mailbox not found
– is_blocked.For assistance forward this error to
– 550 Invalid Recipient
– host or domain name not found. Name service error for type=AAAA: Host not found
– not our Customer
– a problem occurred during the delivery of this message. Please try to resend the message later. The following organization rejected your message:

I have read through 550-5.1.1 and I do not have the time to do all that stuff
