20th August 2015 : Unable to send email using Virus Check service

Thank you very much for using Asahi Net.

Some of our users of the Asahi Net Virus Check service have reported problems when attempting to send email.

We apologize for any inconvenience this has caused our users.

We are working towards resolving this problem and in the meantime will supply more explanation below.


1. Affected: Those who are using the Asahi Net Virus Check service and who use Mozilla Thunderbird 38 (Thunderbird) as their email client.
2. Issue: An error message appears at the time of attempting to send email; the email is not sent.
3. Cause: An unconformity between Asahi Net's mail servers and the Thunderbird mail client.
4. Action: We plan to resolve this problem during the next maintenance of our mail server. We will announce the timing of this later on our Support page.

Should you be an affected user, we are sorry to trouble you but ask that you use another email client instead of Thunderbird until the problem has been resolved, or should you need to keep using Thunderbird please try making the following setting change.

Thunderbird settings change
1. From the Tools menu, select the Account Settings option.
2. Click the Server Settings option for the Thunderbird account you have created for Asahi Net email.
3. Under Security Settings change the Connection security setting to None.
4. Click the OK button.
