Steps to reproduce:

I have two IMAP accounts, say #1 and #2. Messages arrive in account #1. Filters are set for the inbox folder of account #1 to first copy the message to the inbox folder of account #2 and then move the original from the inbox folder of account #1 into a another subfolder of account #1. 


Actual results:

All messages are moved into the subfolder of account #1. About one third of the messages are not copied into the account #2 inbox folder before as they should. 


Expected results:

I expect to have two identical copies of all messages in the IMAP inbox folder of account #2 and the subfolder of account #1.

Filter settings for the inbox folder of account #1 in detail:

Just one filter, in my case named "copy_move". "Manually Run" and "Getting new mail" are ticked. "Filter before Junk-Classification" is selected. "Archiving" and "After sending" are not ticked. "Match all messages" is selected. Two actions are specified in the following sequence: "Copy message into [Inbox folder of account #2]" and "Move messae into [subfolder of account #1]".
