Our mail accounts at boamar.com cannot send mail at all, even a new account just created got the error 554 5.1.8 Sender address blocked.

We acknowledge that one time we use one account to send mail possibly tagged as a campaign mail.

The nature of our business is to design and manufacture swimwear clothes. 

From now we just need and will use mail only for communication purposes with our clients and coworkers.

Looking forward a response.
