Smtp error: 501 syntax error, parameters in command "RCPT

…To: ..CompanyName@DomainName.Co.Uk Notify=Never" Unrecognised or missing error.

We receive the above when using iNotes on R6.5.3 inconjunction with a R5 Mail Template. R6 Mail templates work fine.

We are in the process of upgrading our users to R6 but it will be a lengthy process So a short-term solution to above is required.

Both Server and Config documents for out SMTP servers have been checked and then re-checked for any errors. SMTP mail has worked fine in the past in a mix environment and no changes have been made to either the OS or Domino software.

Any ideas?

Found fix, there is a ibm technote suggesting the issue and fix to upgrade to r6.5.3 from r6.5.1.
