The Associated File is produced during document formatting by the Spooler. If the form contains an Associated File entry for SMTP Email (SMTPTo=emailto@domain.com) or the Email tab within Queues contains a direct email to address, an email could be sent.

These additional conditions are required to send the email:

Queues, Process tab, Associated file entries: is NOT set to Ignore

Email address is properly formed in the SMTPTo Associated File entry:

SMTOTo entries with blank email addresses are ignored (effectively do not exist)

Email addresses without an @ will cause SMTP to fail - they look like web sites - (see KB).

Email addresses with multiple @ or . (full stop) symbols will fail but SMTP will be recovered after that transaction (from Version 7.4.004).  See KB.

Assuming the above conditions are met, the Spooler will fulfill the requirements of the Email tab within Queues and deliver the email to SMTP. Delivery to SMTP is the Spooler's last connection with SMTP Email, errors detected by SMTP will need to be followed up via SMTP.
