When reporting a problem, be sure to include the following
information.
-
A summary of the problem. Please do not just send some
logging without explanation of what YOU believe is wrong.
-
Complete error messages. Please use cut-and-paste, or use
attachments, instead of reciting information from memory.
-
Postfix logging. See the text at the top of the
DEBUG_README
document to find out where logging is stored. Please do not frustrate
the helpers by word wrapping the logging.
-
Consider using a test email address so that you don't have
to reveal email addresses or passwords of innocent people.
-
If you can't use a test email address, please anonymize
information consistently. Replace each letter by "A", each digit
by "D" so that the helpers can still recognize syntactical errors.
-
Output from "postconf -n". Please do not send your
main.cf file or 400+ lines of postconf output.
-
Better, provide output from the postfinger tool.
This can be found at
https://ftp.wl0.org/SOURCES/postfinger.
-
If the problem is SASL related, consider including the
output from the saslfinger tool. This can be found at
https://postfix.state-of-mind.de/patrick.koetter/saslfinger/.
-
If the problem is about too much mail in the queue, consider
including output from the qshape tool, as described in the
QSHAPE_README file.
-
If the problem is protocol related (connections time out
or an SMTP server complains about syntax errors etc.) consider
recording a session with tcpdump, as described in the DEBUG_README document.
