## DESCRIPTION
pam_smtp is a Linux PAM module which provides a way to authenticate users against an SMTP server.

On success it returns PAM_SUCCESS, otherwise it returns PAM_AUTH_ERR, PAM_SERVICE_ERR, PAM_BUF_ERR or PAM_PERM_DENIED.

No credentials are awarded by this module.
## BUILD
The source program is a single C++17(and newer) file.

Requires: pam-devel, libcurl-devel

```bash
$ g++ -O2 pam_smtp.cpp -o pam_smtp.so -shared -lpam -lcurl -fPIC
```
## USAGE
```
pam_smtp.so <server[:port]> [starttls|tls] [@domain_name]
```
If ```@domain_name``` is not omitted, ```username``` against the SMTP will be ```PAM_USER@domain_name```.
