Please find my response to them herewith:
Thank you for your previous email.
Firstly, I do not think you are scrolling down in the outputs to observe the log printouts.
I have therefore adjusted those outputs so that the log data appears first. That way, you are less likely to miss it in the way you have suggested.
Secondly, I have looked carefully back in the history of this ticket. It was escalated to you for a reason. You have suggested nothing that I and those who came before you have not already tried and observed.
I am now of the opinion that this is never going to get fixed.
The only way I can get the from addresses I want, at the present time, is obviously to physically adjust the default output addresses personally myself every time, in the Fxxxxxxl settings.
Please confirm to me that the ONLY thing I need to do is adjust the physical default from address so that over the next couple of weeks so I can get the effects I want.
I rather think there are at least three locations in which I must make the necessary adjustments. I would like confirmation on that fact so I do not use up your time further. What are the three (if memory serves me correctly) adjustments I must make in my Fxxxxxxl settings so I can guarantee the effects I want for the three different domains I manage?
In the mean time, I think it best I start researching to find an alternative email provider, because Fxxxxxxl and I have now gone around in a very big circle right back to where I first started. Having returned to that (being the things you suggested I do, which others before you suggested and that I have already done) then since my problem is still unsolved, it is now clear to me that it is not going to get solved, and so I must find an alternative.
Until such time as I find an alternative, then please help me ensure that my future mailings over the next couple of weeks go smoothly which is I am sure what both you wish and I wish, for I really do not like wasting your time like this. Please therefore outline to me all the locations in my Fxxxxxxl specifications that I need to so I can get the effects I want of a changed default set of parameters for each of my mailings ... and so that my customers get the correct from address for each of these when I email to them.
Thank you for your kindness,
I think I have been as clear as any human could be.
