Bug ID: 3092
Summary: synprot error should invoke notquit ACL
Product: Exim
Version: 4.97
Hardware: x86-64
OS: FreeBSD
Status: NEW
Severity: bug
Priority: medium
Component: ACLs
Assignee: jgh146exb@???
Reporter: Lena@???
CC: exim-dev@???
Documentation says:
When the not-QUIT ACL is running, the variable $smtp_notquit_reason is set to a
string that indicates the reason for the termination of the SMTP connection.
The possible values are:
...
bad-commands Too many unknown or non-mail commands
connection-lost The SMTP connection has been lost
...
"connection-lost" works as intended. But:
In my config I have smtp_max_synprot_errors = 0
For a test I included into the very beginning of the notquit ACL:
warn logwrite = :main,reject: $sender_host_address notquit_reason:
$smtp_notquit_reason
Then I connected (with telnet) and gave two commands:
ehlo test
invalid
In mainlog:
SMTP call from *** (test) [***] dropped: too many syntax or protocol errors
(last command was "invalid", C=EHLO)
no MAIL in SMTP connection from *** (test) [***] D=12s C=EHLO
The notquit ACL isn't invoked. For me it's a bug, I need notquit ACL in such
cases to catch bots.
