Surprisingly, though I like Sonic, incl. Tech Support, overall: 3/3 Tech Support employees did not know the meaning of RR notices. And the last 2 of them said try Sonic Forums.
Or does that RR JUST mean the intended recipient's (IR's) e-mail box ACCEPTED my e-mail?
OR does RR VARY in what it means, or get "told to get lost", depending on the software features of IR's e-mail box?
Like, could RR realistically possibly mean my e-mail was directed to the IR's Suspected Spam or Suspected Malware folder?
2) And why have I NEVER, in over 2 months/~10 e-mails, gotten a "delivery status notification" (DSN)?
Even though I've checked the box for a DSN, like I do for an RR, EVERY time I send an e-mail where I NEED, not just want, that proof of delivery and proof of opening. And I HAVE gotten RR's for all those e-mails. (I've never sent a WebMail asking for ONE OR the other)
So, assuming a delivery can be done, and can be confirmed to me once done: Is that the ONLY situation I would get a DSN?
If so, why don't I?
Thank You, helpful repliers I anticipate,
