Hello,

I have Postfix/Courier-IMAP/LDAP up and running fine on a suse 9.1 box. I now want to add maildrop for filtering. However, I am getting seg faults from maildrop, whether from within postfix or from the command-line.

I have scoured everywhere to try to find out what is causing it, to no avail. I would really appreciate any help here.

Following are my configure arguments used when compiling (1.7.0.20040907), as well as the output of:

cat /tmp/test | strace -o /tmp/t.out maildrop -d valid-user

From the strace I can see that the LDAP query is succeeding, but maildrop dies shortly after that.

How can I get some decent debugging out of maildrop when in delivery mode?

# Configure line: ./configure --enable-maildirquota --enable-maildropldap --prefix=/usr --enable-trusted-users='root vmail postfix' --enable-trusted-groups='root postfix postdrop vmail' --enable-syslog=1 --enable-DEBUG --enable-maildrop-uid=vmail --enable-maildrop-gid=vmail --without-db --without-userdb

strace output:
