Hi all, I've made a test on the MXToolsBox and here is what I get : An idea how to resolve this transaction time ? Thanks. Kind regards.
Do you know how the transaction tme was tested? If its a full roundtrip incl. spam scanning, then 5 sec are normal as the sacn includes text analysy and also network checks.
Are you using some blacklist (i.e. postscreen)? I saw the same with mxtoolbox for the first attempt. The 2nd check is much faster.
Maybe one of your lists is very or slow or outdated. You can disable one or mor lists and run the check again.
