Moving mails from one account to another with attachment bigger than 10 MB
I've got 2 email accounts. I need to move all emails from one account to another. It was always very easy. To do this I have to grab an email or several emails and put it or them into folder on another account. Unfortunatelly from several months it is working only for emails up to 10 MB. Whenever i try to move an mail with attachment bigger than 10 MB nothing is happening. That email stays in previous account. It doesn't work even with copying emails more than 10 MB.
In activity monitor during moving that big file i have got log, which is not changing: "biuro@......com.pl: sending authentication information..."
Can someone help me with that problem?

Are the accounts with the same provider? Or does the target provider not allow messages above a certain size? Note that a message with a 10MB attachment results in a message approx. 13MB due to encoding overhead.
Accounts IMAP are from diffrent providers, and there were never any limits. It just stoped working one day. I can still move emails from one account into local folder but I cannot move it back (from local folder to one of my accounts). And last thing. When I am sending big file (more than 10 MB), that file is sending correctly but it is not writtening into send folder (I can write it only into local folder).
I will ask my providers. Maybe they have made any limit.
My providers haven't done any limits in any attachments. So my problems are in Thunderbird.
Can you run the computer in Windows safe mode and see if the problems remain with TB? That would test the possibility there's some other program, e.g. security or AV, acting on email and slowing the process.
