emails are being resent without my knowledge

more options

In the last week, I've had a couple of emails being resent to their original recipients again, without my knowledge and without my setting up a future send time/date. My email client (runbox.com) doesn't offer delayed send options, so I believe the problem is coming from Thunderbird. Is there a way to check, and a way to stop it? One of the re-sent emails was resent 6 weeks after it was originally sent, and the subject has long been resolved and finished; it was embarrassing to have the recipient think I was raising the issue again.

I only know about 2 emails being resent (one twice, one once) which is itself odd, as they were originally sent to different addresses and on different dates.

re :One of the re-sent emails was resent 6 weeks after it was originally sent,

Thunderbird does not send anything without you sending it.

I'm trying to think of a plausible reason for what may look like a resend. Is it possible, at some point in the past, you tried to send and could only use 'Send Later' or you temporarilly lost internet connection - which put that email in the 'Outbox' - you may not have been aware that the first attempt got sent to Outbox - then you tried again and it got sent out. But there was still an email ready to send in 'Outbox' then when you exited or restarted you got a prompt to send unsent messages so you said yes ?

Is there a copy of that resent email in the Sent folder?

Do you use an addon called 'Send Later' which does offer to delay sending of email ?

I said runbox was my email client, when I meant my email server......Thunderbird is my email client. Sorry about that.

I do have a Send Later addon, but I rarely use it. Much more likely is the possibility that I temporarily lost internet connection (not unknown out here in the boonies) - and that would explain why it only happened to a very few emails.

My curiosity is satisfied, thanks.
