Hey there,
I have quite a few users complaining about not being able to receive messages from customers or potential customers. Senders are getting the dreadful:
host ocean.mxroute.com [195.201.59.214]
SMTP error from remote mail server after end of data:
550 “This mail cannot be forwarded because it was detected as spam.”
Putting email addresses / domains in whitelist is not an option because in most of these cases, the senders are potentially new customers and thus unknown.
I can understand that losing potential customers/sales is a pain and sympathize with them. So I’m sad to even think about having to move those mailboxes to different service(s). Before I do that I would like to ask if there is anything else I could do.
Do you think it will make any difference setting a custom threshold (e.g. to 10 or higher) in the (per mailbox) Spam filters settings?
Is there anything else I could try?
