Actually, Im possibly a bit late with this, but this was one of my two major gripes with PN.
Around 3 years ago, when I requested a change to MX relay... bang... no emails to force9.net.
Called up CSC who told me, and wait for this one, 'Its not valid, and should never have even worked at all, and I dont know why it stopped.'
Well, after countless phonecalls and tickets to people, with headers and screenshots, proving that the emails *did* in fact work, but there was a problem.
I argued that it *had* worked, because I had all my emails pointed to it and they got them quite alright! So what did they do?
Nothing, despite being able to prove it works, it was a case of, 'oh well, its broken now, and we dont think it should work, so we're not going to fix it..' Not ideal, to say the very least.... I did find my welcome email a while after this, and guess what! It shows the .net addresses, so did this slip below the net?
Well, the CS agent didnt, in fact, when I was CUT OFF for non payment of a bill, in turns out that my DD had been deleted...
Now, it wasnt me that binned it...
Basically, Ive said in the past that there were only 2 things that massively bugged me about PN/F9 and those are:
a: ) Messed up orders, things going missing and being deleted.
b: ) The email platform. I tried to use my own email platform, but the .net stopped working, so even that broke!
