Hold Systems Network Architecture Distribution Services queues

You can hold Systems Network Architecture Distribution Services (SNADS) distribution queues, which the SMTP application uses to distribute e-mail. This will provide you with extra protection to limit distribution of e-mail.

To hold the distribution queues, enter the following commands on the character-based interface:

HLDDSTQ DSTQ(QSMTPQ)PTY(*NORMAL)
HLDDSTQ DSTQ(QSMTPQ)PTY(*HIGH)
