G'day, I'd like to use Mailtrap on ACF 2021 Dev Edition. I cannot get the Mail Server settings to verify: I get "Connection Verification Failed!" I populate the Mail server with their suggested values ( sandbox.smtp.mailtrap.io, and the supplied user name and password ). Following their troubleshooting guide, I can telnet to the server, so I don't think the connection is blocked. I have tried the 4 different port numbers they suggest ( 25 or 465 or 587 or 2525 ). I have tried "*Enable TLS connection to mail server"* both on and off. Do you have any advice? Things to try? ( Alternatives even? ) Where I work, the mail server is becoming more locked down, which makes it tough to use our mail server to test cfmail output locally. Thanks,
