'>'   end   -- escape double quotes in file name   filename = filename:gsub('"', '\\"')   -- message headers and body   settings.source = smtp.message({     headers = {       to = table.concat(to, ', '),       subject = subject,     },     body = {       {         headers = {           ['Content-Type'] = 'text/html; charset=utf-8',         },         body = mime.eol(0, message)       },       {         headers = {           ['Content-Type'] = mimetype or 'text/plain',           ['Content-Disposition'] = 'attachment; filename="' .. filename .. '"',           ['Content-Transfer-Encoding'] = 'BASE64',         },         body = ltn12.source.chain(           ltn12.source.string(filedata),           ltn12.filter.chain(mime.encode('base64'), mime.wrap())         )       }     }   })   -- fixup from field   settings.from = '<' .. tostring(settings.from) ..

Dear all,
further to this, I would like to save in HL an image of a cam and sending it by mail or pushover to a customer. The goal is the following:

- when there's a bus event, image of the cam (obviously I have to verify if cam can save image to an external storage like homelynk) I would like to send the image saved to a customer via mail or via pushover.

What do you suggest about it?

Thanks.
