# lws api test smtp client
Performs unit tests on the lws SMTP client abstract protocol
implementation.
The first test "sends mail to a server" (actually is prompted by
test vectors that look like a server) and the second test
confirm it can handle rejection by the "server" cleanly.
## build
Requires lws was built with `-DLWS_WITH_SMTP=1` at cmake.
```
$ cmake . && make
```
## usage
Commandline option|Meaning
---|---
-d <loglevel>|Debug verbosity in decimal, eg, -d15
-r <recipient@whatever.com>|Send the test email to this email address
```
