Below are some of the methods used to remedy email sending and receiving errors.
Method 1: Confirm that your e-mail server settings are correct
This applies to all email programs, not just Outlook. If you use
Outlook, Eudora, Mozilla Thunderbird or any other email program, ensure
that the POP and SMTP server settings are correct.
To check individual email account login information log in to
SmarterMail as postmaster (or any other user who has Domain
Administrator permissions) and go to "Domain Settings >> Email
To confirm that the username password are working correctly, log into
webmail using the username/password for the account in question.
If you can log into webmail, check the POP3 Server and SMTP Server
settings in your email program. Knowledge Base articles detailing how
to check or change these settings for some popular email program are here
Method 2: Examine the configuration of your firewall software
In order to test this you will have to temporarily bypass your local
firewall software (Norton, McAfee, ZoneAlarm, etc.) or hardware
firewall (Linksys, Netgear, or other router, network device provided by
your ISP, etc.). Consult your ISP, hardware or software manufacturer's
documentation for instructions related to temporarily bypassing the
Method 3: Check your antivirus vendor's Web site for additional suggestions
Antivirus software is a common cause of email connection problems. If
you changed the SMTP server settings in Outlook the antivirus software
may not have detected the change, or is blocking the traffic or port
for some other reason. This Microsoft Knowledge Base article
includes links to most antivirus software vendors support or troubleshooting pages.
Method 4: Determine whether your modem is functioning correctly
If you are using a modem and can access the internet this is not a
likely cause of email problems. If you are using a broadband/cable/DSL
connection, you can rule it out as a source of email errors.
Note however, that many ISPs block port 25 for outgoing mail
So we also provide outgoing mail service on port 8889. If you have ruled
out anti-virus or firewall interference, try changing your SMTP setting
from port 25 to 8889.
Method 5: Verify the Maximum Transmission Unit (MTU) size that is set on your router
We have found this to be a frequent cause of email errors in the past. Read the relevant section of the Microsoft article
to determine whether this may apply to your home configuration.
Method 6: Remove and reinstall Outlook Express
Outlook Express can also be a frequent source of email errors, and
removing and reinstalling the program can resolve them. Outlook and
outlook express are prone to corruption of their configuration,
sometimes just in the process of changing settings. If the above
methods do not resolve your problems, or are not applicable, please remove and reinstall
Method 7: Create a new e-mail profile
In most cases the prior steps lead to a resolution. But if they do not, try creating a new e-mail profile. The Microsoft article
has links to articles detailing methods to create a new profile.
Method 8: Delete suspicious messages from your mailbox
Many times an email message with a malformed or otherwise damaged
header can cause mail downloads to stall or fail completely. If you
suspect this may be the case, log in to your email account using
webmail and delete any spam
or suspicious messages.
Method 9: Verify that all SMTP e-mail addresses in a distribution list are valid
If you are sending mail to a large number of recipients, an invalid
address in the list can cause an error. Check your recipient list for
obviously invalid addresses. If none are found, try breaking your list
into smaller sections, in an attempt to locate the invalid address.
