I have enabled the SMTP Email action and it is working fine but I would like to know what the parameters refer to. Is there any explanation of what the parameters mean? Here is an example of what I mean. I have replaced some customer-specific labels with ***. et, st, re are presumably the start, end and resolution times (in unix epoch time at a guess). What do tab-in=, tab-tv= and tr= refer to?
Any help would be much appreciated.
