it means (normally) that your sending the mail as joe_blow@ somedomain.com and your SMTP server you are logging to with is with the credentials of jane_smith@ otherdomain.com. They must be the same address.
Odds are Gmail?

How to enable in XenForo get error log MX Server?

 

[Mike]

I'm not clear what you're asking. The error in the first message is coming from your SMTP server. There's no other logging that XenForo would do.

No, rented server.

The error you posted in the first message is coming from the SMTP server you entered details for in XF. XF is just reporting it. For any specific errors from your SMTP server, you need to contact the provider.
