+ * There is a deadlock situation when ud-mailgate gets a mail claiming
+ to be from itself:
+ - ud-mailgate opens and locks the replay cache
+ - verification of the mail fails for whatever reason
+ - a reply is sent (to itself)
+ - exim tries to deliver the mail by directly calling ud-mailgate
+ - ud-mailgate tries to acquire the lock -> deadlock
+ Fix this by changing when we open the replay cache, and unlock it
+ as soon as we are done.
