Email Problem: Could not deliver the message in the time limit specified 5.4.7
I was wondering if anyone could point me in the right direction on an email problem we are experiencing.
We are currently waiting for some automatically generated information from Edexcel. After many phone calls to edexcel, i have found out why the emails are not coming through, apparently edexcel are getting bounce backs from our mail server which no-one has told me about. The error they are getting is Could not deliver the message in the time limit specified error number: 5.4.7.
Is this a problem at my end or their end? and how do i sort it out.
