After sending email to subscribers I've received this error record in error log on admin side:
Mailbox unavailable. The server response was: sorry, no mailbox here by that name (#5.1.1)
How to fix it?

Could mean a lot of things.

Usually "mailbox unavailable" is a response from the destination server that indicates their spam filter has ignored your message.

Or it could mean the mailbox doesn't exist. Or that it's full. Or that the receiver doesn't allow inbound messages that aren't on their approved senders list. Or that the mailbox name isn't even valid.

When an SMTP error comes back, there's always an SMTP error response code like 501, 504, 505 etc. What was the complete error message?

I'm using the same email like in :
Customer Order Notification
Low Inventory
Order Shipped
and other
I've only one email!
I think it happened because no SMTP Authentication when I sending from Email Lists - ints look like that sending from localhost and my mail server do not allow to send email without Authentication (security - SPAM PROTECT)!
If I can setup the SMTP Authentication (on admin side) for mailbox from I sending emails to subscribers than everything will be ok!

This message seems to be for Email address which doesn't exist. You may have some Email address of this kind in your list.

If you only have 1 email address for all your store emails, ALL your server-side emails would fail. Nobody would get any order confirmations, shipment notifications or anything else. I don't think it's an SMTP Authentication error.

If the error occurs when sending to a mailing list, your mail server probably has a volume-throttle enabled. In other words, they might only let you send a specific number of emails within a certain period of time.

You've had problems with email before. Perhaps it is time to move your email to a different provider that offers better service. Or host your own email.

This is my own email server!!!
And I do not think that is a problem with it!

Ok.

If you think it's an SMTP authentication problem, turn that requirement off on your mail server and see if the problem goes away.

I sending about 10 000 emails everyday from my other websites with authentication without any problems, the authentication - SPAM PROTECT
if I'll turn off it I risk to recieve spam or spamers can using my eamil server fo sending emails!
