Is the Email address right?
Your email settings are correct and you were able to send/receive email before.
The most common problem experienced by users is an incorrectly addressed email message. Most email programs will queue email messages before sending them. If one message is incorrectly addressed, the mail server will refuse to send it and all subsequent email messages will not be sent.
This problem is common in Outlook software as well as some Netscape email, Internet Mail etc.. To fix this problem you will need to launch your email software and change to the folder outbox. See the list of all email queued to be sent. Double click on the first email message to open it. Check that the email address is correct. The email should consist of a valid username at a valid domain name, such as: support@tc3net.com. There cannot be any spaces between the characters. Please be aware that a fake email address will often be refused by the server, so this may also be the problem. If you suspect this then delete the queued email and try sending a new email. An example of incorrectly address email would be: to: John and Merry.

Large email Attachment
If your settings are fine and email addressed correctly, then make sure that the email you are sending is not larger than 5MB Remember that when you are sending a binary file like a picture or a document, those files when transferred through the mail server will grow in size. If you are sending a file, which is around 3.5MB, it might in fact in an email reach close to 5MB, depending on that file type. Mail servers talk to each other in text so the files you are sending are turned into ASCII before being transferred across from one server to another. That makes them grow in size.
If the file that you are sending is too big, try compressing it. Good software to compress files is WinZip.
You can also use some software to break the file into smaller parts. Make sure that the person who will receive it has the same software and is able to put the file back together. Some Outlook email programs will have the option to break a file into smaller parts before sending. Check your help section in Outlook for those options and for instructions on how to use the feature. The receiver should have the same software to be able to decipher the message.

More Hints on Sending Attachments
If you are trying to send an attachment from another drive across a LAN (Local Area Network), you might not be able to send it. Copy the file first to the computer you are using the mail software on and then try attaching it and sending.
Make sure that the file you are attaching is not opened in another software or program. You might have problems sending it too.

No Relay Error
If you are connected to another provider and trying to send email through mail.tc3net.com you will not be allowed to. Most ISPs do not allow relaying through the mail server.
Incoming mail server recognizes you by your username and password, so you can check your email no matter what provider you are connected through. Outgoing mails server, the server that handles sending of your email, recognizes you by the IP address, the unique IP address that you are assigned when you connect to TC3Net. When you connect to another provider our SMTP server will not recognize you as TC3Net user. You will need to use the SMTP Outgoing Mail server of the provider you are dialed into.
If you are on a local area network and having problems sending email, you might have a specific local mail server to send email through. Please confirm your mail settings with your Local Area Network Administrator.
