Recently, I am unable to send email messages to two of my clients from one of my computers on my network. I am able to send email messages to these clients from other computers on the network.

Here is the error I am receiving:

Your message was rejected by mta7.am0.yahoodns.net for the following reason:

Message not allowed - [320]

The following recipients did not receive this message:

<tnichczynski@yahoo.com>
Does anyone know how to fix this problem?

Thanks for your reply.

My computer was off by exactly 1 hour.

What is strange that only two of my contacts were being blocked.

I just sent both of these contacts test email messages to see if fixing my clock solved the problem.

Edit:

This did not solve the problem as both of the email messages I just sent were blocked.

No, unfortunately I did not check the DATE. The date was off by one month. I corrected this, and sent a test message to one of the contacts I was having a problem with.

I did not receive and immediate error reply like I did previously, so hopefully this fixed the problem. I will post here again when and if I receive a reply to my test message.

Edit:

My email was received by the contact I sent it to. Hopefully, this will fix the other contact I could not send an email message to also.

Thanks for you help on this problem. It is much appreciated.
