All my Workflow processes use asterisk in the attachment tab of the Send Email plugin for attachments. (when attachments are marked to be zipped in the plugin)
E.G.
D:\Client\Payslips\Proofs\*.csv
D:\Client\Payslips\Proofs\*.pdf
Now that we don’t use regular smtp I have to use the Secure Email Output plugin. I noticed that I can’t use wildcards in the Secure Email plugin.
The best approach would be to use the Workflow to create a zip archive and hold it in a temp folder. Then in this plugin, supply path/filename of the archive either as a hard coded value or as a workflow variable.
