Bug ID: 2036
Summary: RFE: report IP address of remote host used in callback
verification in smtp error message
Product: Exim
Version: N/A
Hardware: x86
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: General execution
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
RFE: Report which smtp host was being used for verification in exim 550 error
message.
So to replace
"Verification failed for <%s>\n%s"
with for example
"Verification failed for <%s> when talking to %s\n%s"
(where that second %s would be ip of host used in verification callback)
Now when bounce message happens like:
SMTP error from remote mail server after RCPT TO:<[email protected]>:
550-Verification failed for <[email protected]>
550-No Such User Here
550 Sender verify failed
there is no way to be 100% sure that remote host, when doing verification
callback, was actually connecting to proper hosts (ie. these handling sender
domain).
With "Verification failed for <[email protected]> when talking to
93.184.216.34\n..." it would be obvious and easy to debug/diagnose.
