we are facing a problem with sending mails to some domains, the mail server is working fine we can send and recive emails for aproximetly all domains but some we are facing problems with, and some we face delays in delivering the mails, so it will take about 2 or 3 hours to be sent or to be delivered to us from certain domains.
these errors some times are sent back to us:
There was a SMTP communication problem with the recipient’s email server. Please contact your system administrator.
<xxxxl.xxxx.dom #5.5.0 smtp;550 #5.7.1 Your access to submit messages to this e-mail system has been rejected.>
well can aynone please help in this issue???
Otherwise, on using a dynamic ip address, you will get much more e-mail-rejections.
I would suggest to contact one of those recipients and ask about such problem.
The IT-Service should be able to track down, why your e-mails gets rejected on their mail server.
The original poster should always write the last response !!!
Let us know, if the problem is solved !!!
