Secure Email Input
The Secure Email Input task captures a POP3 or IMAP email message with SSL or TLS
encryption.
Note that this plugin cannot be used on a Windows instance that uses a multi-byte language
(e.g. Japanese, Chinese). The workaround is to either use a different Windows language or use
the standard Email Input/Output plugins.
Input
Secure Email Input captures an email and its attachments from the selected inbox when it
corresponds to the rules defined in the General tab.
It will process one email at a time (unless the process is self-replicating; see "Process
properties" on page895) and it will capture the emails as long as there is unread email in the
selected inbox.
Processing
When using the IMAP protocol, filtering is done at the server level and only the first email
matching the conditions is retrieved from the mail server, along with its attachments.
When using the POP3 protocol, filtering is done at the client level. The plugin loops through
every single email located in the inbox, retrieves the email’s header and applies the conditional
logic. The plugin stops that loop when a header corresponds to the conditions. Only at that
point the email's body and attachments are retrieved, and the email that corresponds to the
conditions is deleted from the mail server.
Note
When using the POP3 method, the plug-in will run very slowly if the inbox contains a
large number of emails. Always use IMAP when possible.
Emails retrieved using POP3 are deleted from the server; emails retrieved using IMAP can
either be deleted or marked as read.
