Hello

In Exim 4.96.2, the log_connect_tls_drop() function appeared in the file
src/src/smtp_in.c:


static void
log_connect_tls_drop(const uschar * what, const uschar * log_msg)
{
gstring * g = s_tlslog(NULL);
uschar * tls = string_from_gstring(g);

log_write(L_connection_reject,
log_reject_target, "%s%s%s dropped by %s%s%s",
LOGGING(dnssec) && sender_host_dnssec ? US" DS" : US"",
host_and_ident(TRUE),
tls ? tls : US"",
what,
log_msg ? US": " : US"", log_msg);
}


The value of the last parameter of the log_write function is not checked
before output to the log file. If you use drop without log_message, then
when connecting to port 465 the following message will be displayed in
the log file:


2023-11-09 22:43:41 [36164] H=hostname.domain.tld [1.2.3.4]:17784
I=[5.6.7.8]:465 dropped by 'connect' ACLNULL


In exim 4.96.2, instead of "dropped by 'connect' ACLNULL" it was
displayed "dropped by 'connect' ACL". But in exim 4.96.2 there was no
log_connect_tls_drop() function.
