Forum OpenACS Development: Errore applicativo in trasmissione mail Expected a 354 status line; got: 503 5.0.0 Need RCPT (recipient)

I try to send an email but I indicates this error. Who can help me kindly? Thanks. Greetin

openacs 4.6.2

Hello Patty,
the error you mention is an SMTP Protocol Error saying that the destination server did not find a proper recipient (destination mailbox).

So either your application sends email messages to the wrong mailbox(es) or between your application and the destination server there's a firewall stripping (for whatever reason) the required headers.

Hope this helps,
Maurizio
