Recently, an user said that he can test SMTP account OK but cannot send out any emails in Auto Mail Sender serial products.

Through analyze the SMTP account settings and tested it in AMSSE, AMSBE, Thunderbird, Outlook, I got the following error message every time:

504 5.5.2 <XXXXX>: Helo command rejected: need fully-qualified hostname

In above, XXXXX is your PC name.

If you encounter this issue, you can do the following steps to resolve it:

>> Get the properties for My Computer, next click Network Identification.
>> Click the properties button.
>> Under Computer name specify the HOST / Computer (example: test).
>> Next click the More button.
>> Where it says “Primary DNS suffix of this computer, enter your primary domain name.” click OK and OK again.
>> Now full computer name is: test.domain.com.

** You may have to restart the system**

If you do it with no luck, we recommend you contact your SMTP provider, I think it can be controlled by the server side.
