Why can’t I redirect email to free email services?

Redirect email to Gmail, Yahoo mail, Hotmail etc has been disabled for quite some time now, for us to offer better quality of service on the server email delivery.

All free email service provider controlled their bandwidth and number of email allow from email servers around the world.
Setting redirect means there will be A LOT of email (including spam) redirect from your account to these free services, and could resulting a temporary traffic block on the free email service provider.

This means:

  • you will most likely not going to get the all of redirect email delivered to the free email service provider like gmail, yahoo and hotmail.
  • your email address (or your email server) will be black-listed if the amount of email is over their quota.
  • your email sending to other recipients on these free email address will be degraded too, since your email server will likely under temporary block most of the time.

We hope you understand our intension on such restriction.

Note: If you are using gmail, there is a better way to get the same result by using Gmail's remote POP3 instead. Login with your Gmail account, go to Settings → Accounts and Import → Add POP3 email account.

I cannot send out any email. The error message showed “Cannot find server”. Why?

If you are facing the similar issue, firstly, please check whether your computer has an active internet connection or not. If not, please kindly contact your ISP or your network administrator.
If there is a internet connection and if you are using Outlook or Eudora (non web based) as your email application, please kindly check the settings of your mail application.

I am getting email with partial content or corrupted attachments occasionally, and sometimes multiple copies of such email. Why?

This usually happens when there is a sudden drop on the network quality, or some interruptions in between the mail servers (sender and recipient servers). At this stage, the email transferred is likely incomplete.
Afteroffice Mail server engineer decided to take this further by capturing these incomplete emails, and deliver to our customer account anyway. By doing this, the customer will know that the email has arrived in-time, although corrupted, and serve as an early alert on the email exchange process.
The recipient of the email, in this case, Afteroffice's customer, will be likely getting copies of the same email as the sender mail server will attempt to resend the email again, sometimes over a period of 48 hours.

Why some users cannot receive my email, claimed that my IP being blacklisted

Question:
I am getting a bounced email like the following:

 5.7.1 This system has been configured to reject your mail. An IP address (1.2.3.4) found in the message's
 'Received:' headers is listed by the lookup site 'xx.xx.com.'.  (in reply to end of DATA command)

Answer:
The recipient server has some protection that will reject email that contains black-listed IP in the email. These black-listed IPs covered quite some broadband users' IP, so we believed the recipient server has been over-protected in this case.

To overcome this, you'll have to login with VO webmail and send email from there. Since your broadband IP will not be included in the email sent by using webmail, the chance of getting the email out to these recipients are much higher.

Gmail user can't see my forwarded email, why?

Please be noted as when the email has been forwarded out it will be save as .eml file, and .eml file is not supported by Gmail.
To avoid this problem you can select “text” before you click on “Forward” when you want to forward the email out. Once you select “text”, the forward message will not be sent out as .eml file.
Alternative, you can also click on “Edit” to edit the email before sending out.

Could not send email through mail clients due to authentication error

Typical error from the SMTP session using mail client such as Outlook or Outlook Express:

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was user@domain.tld . Subject 'Subject', Account: 'mail.domain.tld', Server: 'mail.domain.tld', Protocol: SMTP, Server Response: 451 user@domain.tld please authenticate before send', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC78


The user was trying to send the email out without authenticate first by download with POP3 or login with Webmail.

Solution is:
Download the email first to get authenticated, don't just click on the “Send/Recv” button on Outlook Express.
Instead, click and hold on the “Send/Recv” button, select “Receive All” first.
Or you may turn the SMTP authentication ON in your profile.
