All of our 5 NW6.5SP7 give this error when trying to configure the NRM "Mail Notification Configuration" for the "Primary Mail Server Name".


File resolv.cfg (last line empty) looks nice :
domain unil.ch
nameserver 130.223.8.20
nameserver 130.223.4.5


File hosts (last line empty) looks nice :
127.0.0.1 loopback lb localhost
130.223.168.111 HEC11


ping / nwping / nslookup to the smtp server name "smtp.unil.ch" works fine.


Display SMTP Mail Screen gives the following error when "Send config report" :

Connecting to Mail Server (smtp.unil.ch).
Sending from: (<HEC11@[130.223.168.111]>).
Error from MAIL FROM command
Mail connection failed, err = 501.


The only weird thing is when :
I ping "smtp.unil.ch", it gives an error.
I ping "smtp", it's ok.

Is there some wrong settings in TCP/IP / SMTP / NRM / iManager ?

Thanks for an idea ...
