SMTP MailSend issue

I am getting an error "Tha mail server doesn't like the sender name" when sending using the JAL statement - MailSend( "noreply@company.com", "", "Me@company.com", subject, msg). However, I have configured the job error notification to use Account = noreply@company.com and Recipient = Me@company.com and get the job error notification successfully.

Any reason why sending it through the job script is failing with exact same Account and Recipient?

The error message is generic, returned whenever email server connection is rejected. Can you try converting your JAL job to JavaScript job, and see if that works? There is a built-in JAL to JavaScript conversion tool in the Tools menu. The JavaScript engine shares mailing settings and protocols with the scheduler including SSL and TTC settings, basically share the same implementation?

FYI, JAL engine implements its own mailing functions, which are somewhat outdated, and don't support recent security protocols.
