2.7.4 Cautionary notes on sending email (for a Windows host when not using Outlook)
Note the following when sending email on a Windows host without using Outlook:
- Keeping sent items
-
The mail system linkage function does not retain a local copy of email sent without using Outlook.
- Format of recipients in email sending jobs
-
Recipients of emails sent by email sending jobs must be specified by a standard Internet email address.
- How JP1/AJS3 behaves when a domain name is specified incorrectly in an email with multiple recipients
-
When an email contains a recipient with a domain name (the portion after the @ sign) specified incorrectly, the job enters Ended abnormally status and the email is not sent to the recipients whose addresses are specified correctly. Take care to avoid errors when specifying email recipients.
- Timeout periods when sending emails
-
When sending an email via an email sending job, each of the following steps has its own timeout period:
-
Waiting for a connection to the mail server
-
Waiting for a response from the mail server
-
Waiting for the process (telsmail.exe) to finish
These periods can be set by environment setting parameters in the definition key [{JP1_DEFAULT|logical-host-name}\JP1AOMAGENT\mail_link].
The following table lists the environment setting parameters that define these timeout periods.

- About attached files
-
If you send an email without using Outlook, Base64 encoding is applied to any attached files, so the size of the attached files in the email data increases about 1.33 times. As a result, when sending emails with one or more attached files, you need to make sure that the total size of the email data after Base64 encoding does not exceed the maximum value set for the mail server.
