Oh, so you were basically appending a new message in another connection.

Yes, I could take a look at all the IMAP sessions. And I suppose you
haven't disabled index files? You could also try if you can reproduce
this with:

1) Try appending :INDEX=MEMORY to mail_location. Does it change
anything?

2) If 1) fixes it, does just deleting the index files first fix it?

3) The way I was testing it was:

a: telnet localhost 143, 1 login user pass
a: 2 status inbox (messages recent)
b: telnet localhost 143, 3 login user pass
b: 4 append inbox {11}
b: From: foo (enter enter)
a: 5 status inbox (messages recent)
a: 6 select inbox

Does that reproduce it?
