Not directly, in the current version. The Email tab's internal settings list still has a System Default / SMTP / Amazon Ses choice and matching SMTP Host, SMTP Port, SMTP User, SMTP Password and SMTP Encryption fields, but they have been removed from the public Configuration page and are no longer editable there. They still exist as part of an internal onboarding tool restricted to Sprwt staff (an "onboarder" login), so if you need mail sent through your own SMTP server, contact Sprwt support or your onboarding specialist to have it configured for you. Day to day, the Email tab you can edit covers Company Email, Show Text with Email in Footer, System Email - Email Address From, System Email - Name from, System Email - BCC Email Address, and Disable Email Validation Security.
