About schedule reports error messages

Hi All,

We run a PA-500 with PanOS 4.0.8 and setup a schedule report profile to sendout daily custom reports. However sometimes it works and sometimes doesn't.

I would lke to  find out something wrongs, and see many error messages in the mailclient.log by cli "less mp-log mailclient.log".

admin@PA-500-2(active)> less mp-log mailclient.log

It seems due to too many recipients, but we only setup 2 recipients in the Email-Profile.

Is there anyone know what the messages mean?

Thanks.

Re: About schedule reports error messages

Please find the various SMTP codes explained:


This does not seem to be related to PA but the SMTP client.


452 4.5.3 Error: too many recipients

The error message is encountered when the user is exceeding the limit of more than 30 recipients in an email. The list of recipients is inclusive of To,Cc and Bcc. If you encounter the above error, reduce the number of recipients in the email and try again.


Since you do not have multiple recipients  Error code: 452 4.5.3 Error: too many recipients   may not apply.

Thats leads us to one of the following reasons which match the Standard SMTP error codes:

450 4.7.1 Client host rejected: cannot find your reverse hostname
Our inbound servers require reverse hostname for the sender server to be present in order to accept the email. You need to contact the reverse hostname's email admin to add the rDNS to into his server.

450 4.7.1 : Recipient address rejected: Policy Rejection- Quota Exceeded
This error comes from our incoming mail server if user is receiving excessive amounts of mails.

450 4.7.1 Recipient address rejected: Access denied.
This occurs when the recipient address is invalid. i.e., not in form of user@domainname OR if the Recipient address is blocked on server.

451 4.7.1 Service unavailable - try again later;
This error most likely occurs if there is a configuration error with our servers. If you encounter any of the above messages, please contact our support helpdesk with the details.

I would start with verifying the authentication and reverse hostname first.

Hope this helps.

Regards,

Ameya
