Today I compiled exim for the first time and attempted to do some
preliminary tests as described in spec.txt. This was exim-4.12; I
compiled it on two different Linux-2.4.21pre3-glibc-2.2.5 boxes. Both
behaved the same way: compilation and installation went smoothly, -bV
showed no problems, -bt <local username> no problem, -bt <remote
address> no problem, -v local user no problem -- but -v remote user
returned
LOG: MAIN
== glouis@??? R=dnslookup T=remote_smtp defer (-1):
smtp transport process returned non-zero status 0x000b: terminated by
signal 11
LOG: MAIN
Frozen
reproducibly. Running -d -M <id> yielded no further information, other
than that the resolution process completed successfully and a
connection was to be attempted to the correct IP address. Inspection
of the logs on the recipient host machines showed that the segfault
occurred before any connection had been established.
The machines on which exim was compiled both had smail3 installed but
not running at the time the testing was done. Nothing was bound to
port 25 on either (smail wasn't being run from inetd).
I've read what seemed to be the relevant portions of the spec and FAQ
documents and searched for "segfault" in the list archive without
finding anything to enlighten me. Can anyone help?
The configuration was pretty standard:
