Unfortunately the email message is confidential, sorry.

In the meantime, I found another ticket that seems to mention the same  
issue. It says it is not a bug in IMP or Horde_Mapi but the  
BigInteger-Implementation of PEAR. I just tried to install php-bcmath  
(7.0.19-1) and it seems to work fine now.

It's just a bit hard to figure out the behaviour when there are  
multiple possible implementations.

I learned to get rid of PEAR implementations wherever possible.

The issue is solved for me now.
