When sending an e-mail the recipients can be specified in the following headers:
In In-Portal e-mails are configured via E-mail Templates section, which allows to specify each header value for every e-mail template (in addition to what developer specifies, when sending an e-mail using that template):
Also, when developer is sending new e-mail using that template it's possible to specify extra e-mails, that will be different for each e-mail sent out (e.g. e-mail of user, that performed a registration):
Unfortunately recipients added through direct calls to
$email_sender methods are not listed in the E-mail Log.
Determine recipient list, that will be shown in E-mail Log section by analyzing actual sent e-mail header values instead of just looking at e-mail template configuration.
