Sorry, no, that was just an example, to illustrate that pre-login there is no change and after login there is. There is a state transition that happens after login, such that the output to the capability command is rewritten one last time, and then it becomes transparent. Until the state change occurs, CAPABILITY is always and everywhere followed by XAPPLEPUSHSERVICE and “ STARTTLS” is deleted. > what would be interesting is figuring out whether that count is influenced by > anything, e.g., the login, or starttls. to figure that out, you'd need to > issue different numbers of capability commmands before the aforementioned > commands and see how many subsequent capability commands are botched > afterwards. knowing that is important for making the workaround reliable. Here’s “mbsync -a -l -V -DnN” run through the wrapper. The untagged CAPABILITY response (not automatic response code, i.e. “* CAPABILITY …”) only appears once in response to the wrapper issuing a CAPABILITY request once after login. Notice that I have silenced my request and the tagged response, but not the untagged response, so that it appears to be in response to the LIST command. Even though the response contains “XAPPLEPUSHSERVICE”, the server is now transparent—this is how I’m reliably syncing my mail. Hope this clarifies, but if not, I can try to find explicit examples of messages. Reading configuration file /Users/sgucukoglu/.mbsyncrc Channel sync Opening far side store iCloud...
