Dear support,
I found this thread: https://www.symantec.com/connect/forums/error-550-571-requested-action-not-taken-message-refused
Have a problem with my customer delivery: salonedelrisparmio.com
These are bounces:
xxxxxxxx@etfsecurities.com
SMTP error from remote mail server after end of data:
host smtp.etfsecurities.com [5.148.1.5]: 550 5.7.1 Requested action not taken:
message refused
xxxxxxx@StateStreet.com
SMTP error from remote mail server after end of data:
host cluster5.us.messagelabs.com [216.82.250.99]:
553-Message filtered. Refer to the Troubleshooting page at
553-http://www.symanteccloud.com/troubleshooting for more
553 information. (#5.7.1)
There is an external company than manages this account.
If I try to send from postmaster@salonedelrisparmio.com (from my email client). Have no delivery problems.
How to solve this?
Thanks
Marcello
