I've added a rule in acl_smtp_connect to block connections from failed rDNS but occasionally one seemingly slips through. I suspect it's going through a different pathway but why would acl_smtp_connect not block the below event? There's no indication in the logs about "no host name found". Did this go through a different ACL entirely?SMTP protocol synchronization error (input sent without waiting for greeting): rejected connection from H=[152.32.138.230] I=[10.0.0.6]:25 input="\026\003\001\001\027\001"
The connect never happend, due to sending SSLv3 on a cleartext port ( 25 ) . There is nothing you can do here (inside exim), just ignore it. best regards, Cyborg
