Hi there, I'm running into an issue trying to send email with Roundcube. When I click Send, I get an error message that says SMTP Error 220 - Authentication Failed. I tried connecting using openssl s_client smtp -crlf -connect mail.example.com:587 and got these errors 140089437217920:error:0200206F:system library:connect:Connection refused:../crypto/bio/b_sock2.c:110: 140089437217920:error:2008A067:BIO routines:BIO_connect:connect error:../crypto/bio/b_sock2.c:111: connect:errno=111 Has anyone run into this before? Regards, Devin

Please read the post fully, as there are several FAQs covered including your Roundcube error. Also, you have the wrong PHP version as default, you should change that. This is described in that post aswell.
