Hi Arun,
the syntax I use in many and many projects is always the same:
smtp_to( 'xxx@yyy.it;zzz@yyy.it','ETL IQ - SendInfoMail Flow CdG',' Error of execution in flow Jobsrv_CdG_LoadDM_SAP_002',20,20);
Just that command in a script object.
I have no idea which setting ask to Admin team relating the SMTP Server because as I said in another BODS environment the command works perfectly using the same SMTP Server.
Regards.
Vito
