it's a SuSE Linux Box 7.0 with kernel 2.2.16 and different suse
updates installed. cyrus incl. sasl 1.5.24, db-3.1.17 and sendmail 8.11.4
are compiled by source (original source tree).
the imapd 2.0.14 is compiled with the following flags:
./configure --prefix=/usr --with-openssl --with-auth=unix --without-krb
i tried differnt settings in sendmail and imapd to ensure that
only one copy of lmtpd is running, e.g.
lmtpunix cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=0 maxchild=1
btw. if i change the lmtpd source to bypass the problematic
point it will crash also with a SIGSEGV while calling malloc()
but just some "lines" later. does the lmtpd use it's own malloc()
which conflicts with the libc's malloc()?
the sendmail config looks like:
