I know this is an older post, but as people are still responding...
I have to say, I've not seen any mail slot issues of late. It used to be simple to trigger it. Simply sit at a station for a while before attempting to leave - it'd be a nightmare! So, launching the game and, once it, immediately taking off = clear mail slot. Conversely, launching the game, then just sitting there for half an hour before trying to launch = problems.
I got distracted the other day, so was sat in the station for a good thirty minutes before I got moving, was quite surprised that I exited cleanly, no issues.
Being in Open can certainly have an impact, but the not leaving the station promptly thing happens in Solo and low-population Private Groups too. As Morbad says, it's likely linked to how long the instance has been active and more Commanders means it might have been active for a long time...
