Once authenticated you may issue any SMTP command by simply typing it in. It is capable of multiple SASL authentica- tion mechanisms and handles encryption layers transparently. This utility is often used for testing the operation of a smtp server. Also those developing SMTP clients find it useful.</p> <a name="OPTIONS"></a><h2>OPTIONS</h2> <table width="100%" rules="none" frame="none" cols="3"> <tr valign="top" align="left"> <td valign="top" align="left" width="12.7692%"> <p><font size=3><B>-t</B> <font size=3><I>keyfile</p> </I></td> <td valign="top" align="left" width="7.2308%"> </td> <td valign="top" align="left" width="80.0000%"> <p><font size=3>Enable TLS. <font size=3><I>keyfile</I> <font size=3>contains the TLS public and private keys.
