Hello rugdog,<br />
<br />
thanks for the comment. so if i understand correctly, first i will need to add this to /etc/mail/sendmail.mc &nbsp;:<br />
<br />
define(`SMART_HOST', `mail.isp.net')<br />
&nbsp;<br />
and then in /etc/mai/access , i add AuthInfo:your.smtp.host.co<wbr />m &quot;U:&lt;username&gt;&quot; &quot;P:&lt;password&gt;&quot; &quot;M:PLAIN&quot;<br />
<br />

Hello,<br />
we have a new server running CentOS and couple of VPSs on it and we wanted to configure sendmail to use smarthost instead of direct-delivery. i found articles how to do this and it seems pretty straight forward. however, our smart-host requires smtp-authorization (username/password). Is there any way to configure sendmail smarthost configuration with smtp-authorization? Can you please send me how-to instruction and what i will need to do?<br />

Sendmail smarthost configuration with smtp-authorization

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.

Linux Networking

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
