Bug#791870: exim4: can't mail to multiple recipients

[Luis Mochan]

Package: exim4
Version: 4.86~RC4-1
Severity: important

Dear Maintainer,

After a recent upgrade, in 2015-07-05, I have been unable to send mail to more
than one recipient at a time, without regard of whether the second recipient is
included in the To:, Cc: or Bcc: field. I use mutt, and I get the message
  child exited with error 1 ()
when using multiple recipients, but I can send emails individually to each of
them. On the other hand the file
  /var/log/exim4/mainlog
shows corresponding messages such as
  2015-07-08 22:50:51 1ZD2rL-00014i-0P local_scan() function crashed with
signal 11 - message temporarily rejected (size 958)

I also tried to send mail directly from the command line using 'mail' instead
of mutt, with similar results:

$ echo yes|mail -s test mochan at em.fis.unam.mx mochan at fis.unam.mx
Can't send mail: sendmail process failed with error code 1

Regards,
Luis
