Exim builds fine with gcc on SunOS 4 but crashes inside sscanf().

How can I get rid of spurious ^M (carriage return) characters in messages sent from CDE dtmail?

On SunOS 4 Exim crashes when looking up domains in the DNS that have more than 10 A records.

I am experiencing mailbox locking problems with Sun's mailtool used over a network.

Exim has been crashing on my Solaris x86 system, apparently while running DBM functions.

The exiwhat utility isn't working for me on a Solaris 2 system.

How do I stop Sun's dtcm from hanging?

I want Exim to use only the resolver (i.e. ignore /etc/hosts), but don't want to alter the nsswitch.conf file in Solaris 2.

When I try to compile Exim 4.x on Solaris 2.5.1 I get an error along the lines of no such field in struct as 'value.ui32.
