DNS issue? rejected user on seconded email account

[bbyford]

HELLO!

I have serveral email addressess running off a single mailinabox v0.21c installation and working well. My issue is with adding a second email address to a domain which does not have is nameserver records pointing to teh MAilinabox server.

i.e.
email1@domain.com - works fines
email2@domain.com - not working - Sender address rejected: not owned by user

not sure if there’s a issue with the domain DNS or something but I feel like I’ve tried everything and still not working.

DNS settings for domain.com:

•       A                178.62.x.xx
  

@ A 178.62.x.xx
www A 178.62.x.xx
mail A 46.101.x.xx

•           TXT/SPF        v=spf1 mx -all
  

@ TXT/SPF v=spf1 mx -all
www TXT/SPF v=spf1 -all
ns2.mail TXT/SPF v=spf1 -all

•        MX    20        mail.mailinabox.com.    
  

@ MX 10 mail.mailinabox.com.

Sender address rejected: not owned by user

Correct me if I am wrong, but this looks like the verbiage within Roundcube when sending from an alias that is not correctly set up.

OP - Where are you seeing the error message you referenced? Was email2@domain.com set up as a user or an alias?

Hit it on the nose there! it was a last resort and saw that there was an alias set up. after it was deleted the mailbox started working!

Thanks
