You can always find answers to your Xerox questions at www.xerox.com/support .

The 3220 does NOT support SSL, please verify if your email service is requiring SSL transmission. (Port 445 or 587 are indicators of SSL email requirements.) There are free email providers that will still send on port 25 without SSL. Xerox does not provide a list however so you will need to research these yourself.

Instructions for setup scan to email below:
Configure the Machine for Scan to E-mail
IMPORTANT: Obtain the following information from your e-mail service provider before configuring the machine for Scan to E-Mail.

1. What is the host name or IP address of the SMTP server?
2. What port number does that SMTP server require?
3. Does the server require authentication login? If so, what format does the server expect the login? (Does the server require the full e-mail address or just the part before the @ sign?)
4. Does the e-mail server require POP3 before SMTP authentication? If so, obtain the POP3 settings (POP3 host name or IP address, port number, and login name/password).
5. Does the server require SSL or TLS encryption? If so, ask your e-mail provider to provide you with an e-mail server that does not use SSL or TLS encryption as the printer does not support SSL/TLS encryption for e-mail authentication.
   
   NOTES:
   • If you are provided with a new e-mail server to use, questions 1 - 7 will need to be answered again.
   • Xerox does not provide a list of e-mail providers that do not require SSL/TLS encryption for e-mail authentication.
   • If unable to find an e-mail service that does not require SSL or TLS encryption, See theRelated Items below for information on how to Install the Network Scan program for a Windows OS or how to Install the USB Scan Driver for a Macintosh OS. Once the scanned file is stored on your computer, it can then be e-mailed from your computer as an attached item/file in a new e-mail.
6. What is the attachment size limit on the account on that server?
7. What 'From' address will the printer use for Scan to E-mail? The From address should be a valid e-mail address for the e-mail server that the printer will use. Ask the e-mail provider if authentication is required if the login name (above) is allowed to be used for the From address the printer will use.
   
   If you do not know the answer to the questions above, contact the people that control the e-mail server you want the machine to use for Scan to E-mail. The following parties can provide you with additional assistance:
   • If the e-mail server is inside your company's network, contact the E-mail Server Administrator to obtain the required settings.
   • If the e-mail server is outside your company, contact the Technical Support for that e-mail service to obtain the required settings. This may be your Internet Service Provider (ISP), or a 3rd party E-mail Service Provider.

Configure the Machine's E-mail Settings Using CentreWare Internet Services (CWIS)
After you have obtained the above information, configure the machine's e-mail settings using CWIS.

1. Access CWIS. See the Related Items below for additional information.
2. Click on the [Properties] link.

6. Enter the IP address or domain (host) name of the SMTP (e-mail) server in the field provided.
   
   NOTE: If you use an IP address for the SMTP server, verify that the IP address for the server will not change. If the SMTP's server IP address changes, the machine will be unable to Scan to E-mail until the machine's SMTP Server address entry is edited with the new SMTP server IP address. If necessary, contact your E-mail Administrator to verify how the IP address has been assigned to the SMTP server.
   
   NOTE: If using the domain (host) name, make sure DNS is enabled on the machine. By default, DNS is disabled. To enable and configure DNS settings, click on the Properties tab, click on the TCP/IP link under the Protocols folder, enter the required DNS settings for your network in the DNS/DDNS field, and then click on [Save Changes]. Contact your Network Administrator to obtain the correct DNS settings.
7. Enter the port number used by the e-mail server, from 1 to 65535, in the field provided. The default port number is 25. If you use an IP address for the SMTP server, verify that the IP address for the server will not change.
   
   NOTE: If you use an IP address for the SMTP server, verify that the IP address for the server will not change. If the SMTP's server IP address changes, the machine will be unable to Scan to E-mail until the machine's SMTP Server address entry is edited with the new SMTP server IP address. If necessary, contact your E-mail Administrator to verify how the IP address has been assigned to the SMTP server.
8. If authentication is required, insert a check mark in the SMTP Requires Authentication check box.
9. In the SMTP Server Login Name field, enter the SMTP login name.
10. In the SMTP Server Password field, enter the SMTP password and then retype the same password in the Verify Password field.

hi
Most common reason for 'Outlook cannot connect to SMTP server' error is the wrong configuration settings of Outlook. This happens especially in the case of newly configured email accounts.
A mis-spelled mail server name to a wrong port setting in Outlook can cause connectivity issues to the mail server and end up giving error while trying to send or receive mails.
By default, the port settings for mail related services are these, and a connection problem to these ports can lead to Outlook error:
SMTP - port 25 / 587 POP3 - port 110 IMAP - port 143 Secure SMTP (SSMTP) - port 465 IMAP4 over SSL (IMAPS) - port 993 Secure POP3 (SSL-POP) - port 995 There are also chances that some web masters may have duplicate profiles in Outlook, which will have an old mail server configured in it, and therefore would be trying to connect to the wrong mail server.

Check for a typo in the SMTP server address. You might also try smtp.googlemail.com instead (port 465 SSL). I've seen both used.

make sure you have the correct settings.
Incoming:
Username: yahoo email without @yahoo.com Password: Your password Type: POP3 Server: pop.mail.yahoo.com Authentication: SSL
Outgoing:
Require login: Tick SMTP server: smtp.mail.yahoo.com Authentication: SSL/TLS Port: 587/25

I'm pretty sure that the problem (though the machine indicating otherwise) is that gmail requires SSL, and the Scan to Email (server) doesn't support SSL. If this is the problem, you can easily check it out by trying to use some other mail, with another SMTP server, which doesn't require SSL.

the dns setting are not correct apparently.
try these settings and make sure you include the proper port setting

Yahoo Incoming Mail Server (POP3) - pop.mail.yahoo.com (port 110)
Yahoo Outgoing Mail Server (SMTP) - smtp.mail.yahoo.com (port 25)

True to really help you we do need some additional information such as mail client software, and mail service. That being said, some mail services, Like Yahoo! require you to purchase an upgrade to your account to use a POP3/SMTP or IMAP rather than their web interface. You may want to verify that you have your SMTP and POP3 servers are set correctly, as well as ports. How this is done varies based on your mail client software. Normally smtp is port 25 and POP3 is 110, but if you are using ssl, POP3 can be 995 and SMTP can be 465. Also can be verify that any firewall software are not blocking it, how that is done is based on your firewall settings.
