Email settings
In the System info > Email TSI, you can register a list of email addresses that can be used to set defaults in Planon ProCenter . An email record on the Email business object can contain a maximum of 100 characters. It is validated against the following formula, applied by a third party email address validator. It specifies a maximum length per part of the email address, as follows:
User name (64 max.) + @(1 max.) + Domain1 (62 max.) + . (1 max.) + Domain2 (62 max.) + .com(4 max.)
The System settings > Outgoing email TSI is used to define settings relating to sending email.
Planon enables sending mail via:
• SMTP (Simple Mail Transfer Protocol, an ASCII protocol).
• OAuth 2.0 client credentials flow, for this proptocol you can obtain a Planon system app (Planon Connect for Office365 Mailings) which needs to be installed in the Apps TSI.
