My TikiWiki (version 8.4) cannot send email. Configuring it as sendmail fails. I am told that on my server sendmail is /usr/sbin/sendmail, but I could not figure out where TikiWiki expects it to be.
From the General admin page, when I put my own email as "Email to send a test email", I get "test email sent to tjrob at muonsinc.com", but no such email ever arrives. So it looks like sendmail is misconfigured (and this forum probably cannot help with that).
When I configure it to use SMTP, with credentials Thunderbird can use, it still doesn't work.
From the General admin page, when I put my own email as "Email to send a test email", I get the error "Unable to send mailArray ( 0 => Failed to connect to server: Connection timed out 1 => Not connected! ) "
Both Thunderbird and Firefox can connect to the email server I configured, and login with the login/password I supplied. I tried the following combinations:
port 25 / security none
port 465 / security SSL
port 587 / security TLS
