Sets which SMTP server to use.
There are a few combinations possible.
First you can use SendMail.SetSMTPServer with SSL and pass 1 there.
Or you pass 0 for no SSL. Still you can use CURL.SetOptionFTPSSL set to 3 to allow TLS for an upgrade of the unencrypted connection to SSL later.
Some servers don't support unencrypted, SSL or TLS, so only one may work.
And ports can be difficult, too. You can use CURL.SetOptionPort to set a port explicit or include it in the server with double colon on the end. Common ports are 25, 587 or 465.

Alternative to this method you can set CURL.SetOptionURL directly.


Start new email and setup SMTP login:

Set Variable [$EmailID; Value:MBS("SendMail.CreateEmail")]
Set Variable [$r; Value:MBS("SendMail.SetSMTPServer"; $EmailID; EMail::SMTP Server; EMail::SMTP SSL)]
Set Variable [$r; Value:MBS("SendMail.SetSMTPUserName"; $EmailID; EMail::SMTP Username)]
Set Variable [$r; Value:MBS("SendMail.SetSMTPPassword"; $EmailID; EMail::SMTP Password)]
