+\r
+I've just had a good think about this, also because the idea of\r
+abandoning IMAP and using Git has been around for a while and\r
+I have not really wrapped my head around it.\r
+\r
+If the MDA delivers to Git, then potentially, you might get into\r
+a situation where you cannot write your own changes back to the\r
+repo. This is also a DoS scenario: I'll just keep sending you\r
+e-mail, and if I manage to pass your mail filters, I'll basically\r
+commit to your mail repository at regular intervals. Say those are\r
+5 seconds. In order for you to write updates to the repo, e.g. to\r
+update tags, then you would need to pull, rebase, and push all\r
+within 5 seconds, for otherwise you'd try to push non-fast-forwards.\r
+\r
+This a bit unrealistic, surely, but there's a real annoyance in it:\r
+you'd have to pull/rebase/push until a push succeeds =E2=80=94 until you\r
+found a time window between pull and push during which the MDA\r
+didn't write to the repo. This might take a long time. If this\r
+happens in the background by Cron, it's not a real concern, but if\r
+this becomes a UI issue, I wouldn't know how to handle it.\r
