Thank you.
Just in case anyone else hits this. On Illumos it appears that if you
have _XOPEN_SOURCE_EXTENDED set when compiling src/ip.c then connect
will check the permissions on the socket in the file system, which for
the dovecot auth socket is mode 600 and owned by dovecot, not exim. This
seems odd to have the permission checking controlled by the way the
client is compiled rather than the way the server is, but that is what
happens.
Adding:
#ifdef _XOPEN_SOURCE_EXTENDED
#undef _XOPEN_SOURCE_EXTENDED
#endif
to the top of src/ip.c makes authentication work.
