Hi Phil thank you for taking the time to look at the problem. I will ask
for a -M <message id> log. And sorry for not making clear what test were
done for the log files so I rearranged some logs and made a readme for
information explaining the logs. I am also really sorry for the
censoring of the data I totally understand that this is harder to read.
The hosting company of server-a (exim) asked with strong emphasis to
filter all ip addresses and domains directing to there company. I am all
for transparency and easy to read logs, but I will respect there request
for privacy.
server-a is the exim server sending the mail via some webform system
server-b is the postfix server trying to receive the mail
server-a is of an other hosting company outside my scope of control but
i can sent mail to them asking for information and help.
server-b is is my own controlled server, I can generate every logs you
want no censoring needed.
terms that are used for a replacement:
- alpha
- servera
- golf
- 12.34.56.789
exim-server-a-information.txt
this is the information I received from the hosting company it appears
that when the server tries to send mail via a webform there processes
generates signal 11 segmentation fault. probably a library mismatch with
ssl systems or some resource limitation. What commands could be helpful
to receive more information.
openssl-server-a-check.txt
this is a separate test to see if server-a and openssl is not complete
broken this is an incoming test and the problem is outgoing but this way
i can test some certificates. The certificates are full with localhost
and some... there is nothing indicating the relation of the certificated
with the server I don't know if this could cause any problems but I
don't think this is the problem in this case.
openssl-helmwijk-check.txt
this test has nothing to do with server-a it is an test from other
systems making tls connection with the postfix server to test the
delivery of mails. no filters here since it has nothing to do with the
server-a hosting company.
postconf-n-helmwijk.txt
my postfix configuration i also use smtpd -v in the master file, nothing
filtered since it has nothing to do with the server-a
ssldump-smtpd-v-helmwijk-server-a-fail.txt
this is important information from the postfix server that tries to
receive mail from the exim server systems. you can see that when my
server wants to talk starttls the exim server just hangs up the line.
(segmentation fault on exim side) this log is filtered.
I hope this provide some better information about what happens.
Thanks in advance,
Best regards,
Jelle de Jong
