I have a SBS 2011 server.
We have a problem with the outgoing e-mail to external addresses. Intern e-mail works fine.
We send our e-mail with a smart host of our internet provider and the last two days we have the following problems:
* The most of time e-mail needs 4 minutes to send it outside. The e-mail is directly in the queue but it stucks in the queue for a few minutes. The problem exits not always but the most of time. We use GFI mail security & GFI mail essentials for the spam and virus scanning.
Is there anyone who can tell me how I can solve this problem. I will restart the server now, maybe that is a solution
