Hi all,

i just found a lot aof unhandled fragments of emails in my input directory.

The corresponding message in the log is just:


2014-04-20 23:52:03 1Wbzed-0007gr-FE string_sprintf expansion was longer
than 32768

the only file left is the data part :

-rw-r----- 1 exim exim 2549239 20. Apr 23:52 ./1Wbzed-0007gr-FE-D

Interessting is, that no other logline is present, no from, no to log,
nor the host who send it.

It's possible that someone tried it via 127.0.0.1 or sendmail_wrapper ,
but without the header file, we wil never know.

As you can see, it's not just one mail:

Any ideas what could have caused this ?
