There may be a few reasons why you are unable to send email:
1.
Ensure that your outgoing mail server on your POP client is pointing to
smtp.yourdomain.com (where yourdomain.com is your domain name) on port
587 with "My (SMTP) Server Requires Authentication" configured. For
instructions on how to configure your POP client, browse to Configure POP settingsNOTE:
Verizon customers should be aware that their ISP is securing their
network and restricting SMTP access - Port 25 on Verizon is no longer
supported:
http://voices.washingtonpost.com/securityfix/2009/02/verizon_to_implement_spam_bloc.html.
This is the case for many other ISP's as well. Please check with your
ISP for further details.
2.
Some ISP's do not allow their customers to send E-mail out using a
third party SMTP server. Our most recent research has revealed that the
following ISP's require their customers to use their own ISP's SMTP
servers: Earthlink, Comcast, Sympatico, AT&T, Charter
Communications, NetZero/Juno, MSN, and RCN.
If your ISP
doesn't allow you to send E-mail out using a third party SMTP server,
we recommend that you contact them directly to verify their SMTP server
settings.
During our most recent research, we were able to identify the following SMTP server addresses:
Earthlink: smtpauth.earthlink.net (To verify, visit http://www.earthlink.net)
Comcast: smtp.comcast.net (To verify, visit http://www.comcast.com)
Sympatico: smtp1.sympatico.ca or smtp8.sympatico.ca (To verify, visit http://www.sympatico.ca)
AT&T: mailhost.att.net (To verify, visit http://www.att.net)
Netzero: smtp.netzero.com (To verify, visit http://www.netzero.net)
Charter Communications: smtp.charter.net (To verify, visit http://www.charter.com)
MSN: smtp.email.msn.com (To verify, please check with your MSN provider)
RCNL: smtp.rcn.com (To verify, visit http://www.rcn.com)
BellSouth.net: mail.bellsouth.net (To verify, visit http://www.bellsouth.net)
Cox.net:
smtp.east.cox.net (CT, FL, GA, LA, NC, OH, RI, VA);
smtp.central.cox.net (KS, NE, OK, UT, West TX); smtp.west.cox.net (AZ,
CA, NV); smtp.cox-internet.com (for @cox-internet.com customers
in AR, ID, LA, MI, East TX, Tyler). Port 587 may also be required for SMTP. To verify, visit http://www.cox.net Rogers: May require port 587 for smtp. To verify, visit http://www.rogers.com IMPORTANT:
If using port 587, please ensure that you configure your POP client for
"My Outgoing mail server (SMTP) requires authentication".
3. Please ensure that your domain name is fully registered and that it has not expired.
If you haven't registered your domain yet, please browse to https://controlpanel.netfirms.comlogin and follow the steps below:
(i). Login into the members control panel
(ii). Click "Domains"
(iii). Follow the onscreen prompts to register a new domain name
If your domain is already registered with Netfirms, please browse to https://controlpanel.netfirms.com and follow the steps below:
(i). Login into the members control panel
(ii). Click on the Billing/Renewal tab
(iii). Click the renew button next to your domain
(iv). Renew your domain and complete the process
If your domain was registered through another registrar, you have two options:
(i).
If your domain registrar has not yet released the domain name, you may
need to renew your domain name with your domain registrar
(ii). Or if they have released the domain name, you can register the domain name with Netfirms as a “new” domain name
4.
If you are trying to send to a Hotmail, Yahoo, Gmail or other
externally hosted account and the emails are not being delivered to the
respective inbox, please check the spam, junk or bulk folder. For instance:
(i)
If your forwarding address is a hotmail account, please check the
sensitivity of the Junk E-Mail Filter. Hotmail says that "...at
Enhanced and Exclusive levels, wanted messages are occasionally
identified as junk e-mail. Check the junk e-mail folder regularly to
make sure wanted e-mail has not been moved there."
(ii)
If your forwarding address is a yahoo account, please go to the Bulk
folder and check if Yahoo's SpamGuard is turned on. Yahoo says that
"...While we make our best efforts to deliver solicited commercial and
non-commercial email directly to your inbox, a non-spam message may be
delivered to your Bulk folder on occasion. For this reason, we
recommend that the recipient check this folder periodically to ensure
important messages are not missed."
5. If your POP mail client is timing out before the emails are sent out, please click here for instructions on how extend the time-out configuration in your POP mail client (eg. Outlook, Outlook Express)
6.
Verify if the computer you are trying to send email from is running the
Norton Antivirus program. Norton AntiVirus Email Scanning could be
having an adverse effect on sending and receiving your email. Please
click here for instructions on how to send emails using POP mail client with Email scanning disabled from Norton Antivirus.
7.
Verify that the computer you are trying to send email from is not
running a firewall that may be interfering with SMTP traffic on port 25
or port 587. Ensure that if you are behind a firewall or proxy server
that your firewall or proxy server is not blocking FTP on port 25 and
587. For information about disabling firewalls, click here.
NOTE:
As an alternative to checking your mail using a POP client we suggest
that you use Netfirms Webmail available from anywhere in the world at
any time from: http://webmail.yourdomain.com (where yourdomain.com is your registered domain hosted at Netfirms) when you are working remotely.
8.
If your email messages are being sent but being bounced back with the
following error: "Reason: 553 sorry, that domain isn't in my list of
allowed rcpthosts (#5.7.1)" error mean when an email message bounces
back to the sender?", click here.
