One of the improvements that came with the release of FileMaker 18 was additional supported cURL options. Among these are the SMB protocol and the ability to send email with SMTP and SMTPS. These allow you to access a mapped drive and send out HTML emails, respectively.
Using this method can allow access to mapped network drives. The Server Message Block Protocol (SMB protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports and other resources on a network.
These methods can be called to finally send mail outside of the send mail script step. This also fulfills the long-time desired ability to send out emails that contain HTML, complete with whatever CSS you want to attach to it. Additionally, this supports the option to allow attachments in-line, which really adds a much-needed update to the quality and type of emails being sent out through FileMaker.
The added functionality available through the extended cURL supported options keep FileMaker tools on par with the standards expected in the development community. All around, it is a great addition to the platform! You can find out more by going to the new features help page. Happy Filemaking folks!
