When I send an Interac e-transfer, my bank sends me two email notifications. The first is that I have sent an Interac e-transfer, and the second tells me that the recipient has accepted it. Both of these notifications used to say that the sender was my bank, and continue to do that on my ISP's email portal. On Thuderbird, however, the first emails indicate that they are from my bank, and the second ones show that they are coming from my friend "John Smith" (who happens to be someone who sends me occasional Interac e-transfers). This has happened about 5 times now, and has done so over the last two months. This makes me very nervous! If Thunderbird is inserting someone else's name as the sender, and not my bank, is John Smith notified about anything? I do not want my private banking actions communicated to anyone other than me and/or my bank. And why does my ISP's email portal show the sender correctly, and Thunderbird makes up the fact that it is from John Smith? Any help with this would be greatly appreciated. I searched this forum for "Interac" and didn't find anything similar.
