Great to hear that it works!
A few comments to your notes:
- the configuration file is a Tcl script. So all Tcl-substitution rules apply. This is why you can set/use Tcl variables there.
- As mentioned before, the "userinfo" part of URL has to be percent-encoded (RFC 3207). This applies not only to the "@" sign, but also to other funny characters, which are not allowed in the userinfo. To be on the safe side, one can use NaviServer's
ns_urlencode (using here square braces for demonstration purposes; the oauth1 encoding requirements are quite strict):
set credentials {webmaster@celtic-arts.org:xyz+[PWD]}
set userinfo [ns_urlencode -part oauth1 $credentials]
ns_param relay plain://$userinfo@smtp.celtic-arts.org:587
- Be cautious when embedding credentials in configuration files. To protect sensitive information, restrict file permissions for the configuration file, verify user permissions on the host machine, or consider using environment variables or reading credentials from a secured file. Keep in mind that arbitrary Tcl commands can be executed from within the configuration file.
all the best
