In the following, we have listed replies to the most frequently asked questions.
Why is there a delay in delivering my emails?
Since email is an asynchronous medium, we and all other providers cannot guarantee prompt delivery.
Why are my emails being identified as spam?
The spam filter systems comprise a number of different IP-based and content-based filter modules. Nevertheless, an email can be incorrectly identified as spam. Please send us the extended header for any email of this kind.
Does we use greylisting?
In case of unmistakable characteristics that indicate a spamming server, we delay any emails sent from a specific IP address, or reject them completely.
Why are connections between my server and the mc8051 systems being refused?
Please check if your email server’s IP address is listed on an established RBL list. You can use tools like mxtoolbox or heise spam check.. Please contact the list operator directly in such a case.
Additionally, check your server logfiles as of the first occurrence of any error.
Check whether you comply with the standards defined by the RFCs and please take note of our Email policy.
