Hi,

 

I don't know where actually to look for help. Is there any service at Barracuda Networks where I can file problems with sending emails to barracuda-protected websites? I have checked whether our SMTP outgoing IP is not listed at any significant RBLs, but it seems to be clean...

 

I'm running a server hosting multiple domains, and today one of my clients asked me about Post Delivery Failure notification being received from the address, which she could send emails just few days ago. I have verified, that she is unable to send any email (so it's not about heuristics) to any email in the specific domain.

 

Here is the message that she received. She was sending emails from biuro@akademiarozrywki.pl.

We are receiving similar undeliverable rejections.  Did you find an answer?

Hi.

 

I have experience the same issue. SPF record are properly configure and the server is not listed in any RBL database.

 

Somebody can pointing me how to contact Barracuda Situation to report the issue.
