We have implemented HP PPMC 7.5 on IBM AIX machine.After this we found that email notificatons are not working.
We are able to ping the SMTP complient server from the HP PPMC application server's machine. but still the email notifications are not happening.We checke all the possible server.conf parameters for this functionality which are fine.
We even checked the connectivity between the HP PPM application server's machine to SMTP server by telnet on the port 25 which is working fine.
When I checked the server logs I am getting the error which is mentioned below
The explanation for return code 554 documents several reasons this error can be reported. It includes the following text:
In most other cases, however, a recipient mail server will return an SMTP REPLY 554 when its anti-spam firewall does not like the senderâ s email address, or the senderâ s IP address, or the senderâ s ISP server (because, for example, they are listed in an RBL) and where you will therefore either need to have the sender whitelist you in their anti-spam program/appliance, or, worse, you will need to take steps to have either your IP address or your ISPâ s servers (if you send mail through your ISP) de-listed from one or more RBLs (RBL = Realtime Blackhole List â also called Realtime Blacklist nowadays).
