I have been using Thunderbird for about 3 years now, never noticed any problem until recently (2 weeks ago). I currently have five email accounts setup in Thunderbird (@gmail.com, @yahoo.ca, and 3 accounts from my internet provider @bell.net). Two weeks ago I noticed that some of my emails for one (the most heavily used) of my @bell.net accounts started arriving with about 8 hours delay. Example: I have setup my bank account to send me an email alert every time I made a transaction, I made a transaction on April 27, 2021 at 2:54PM, I only received the notification the same day but at 10:xxPM, however the timestamp of the delayed message did show 2:54PM, made two other transactions on May 6, 2021 at 3:33PM, 3:35PM, but received the emails on May 10, 2021 at 10AM; so it took 4 days for me to receive the mails. I called my bank and they told me that it is not due to them. I checked with my bell.net provider and they told me that there is no problem with them either.
Then, just last Friday, I started noticing the same problem for some of my emails to @yahoo.ca email account as well. Example, yesterday, someone sent me an email at 2:31PM, but I only received it at 10:03PM, again with the received timestamp showed the correct 2:31PM. But the problem is not happening to every email to that account, only some.
I have checked my email filters for every account, on both Thunderbird and the website of the provider, but saw no change or issue. I find it strange that two different mail servers are exhibiting the exact same problem, the only other common factor between the two is Thunderbird. Is this a known problem? What could be causing this problem?
