Dear Postfix users,
I manage a postfix server (version 2.5.5)
I set fail2ban to stop brute force attack on port 25 for postfix (and
auth command).
Today there are lots of ip banned for postfix... much more than
usually... (see my log.txt)
Port 25 is set on my server to not allow sasl authentication...
I do not know how to stop this...
Otherwise in logs, there are many entries as this one :
*postfix/smtpd[32347]: warning: TLS library problem:
32347:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version
number:s3_pkt.c:293:*
I desactivate support for SSL3 in postfix configuration... Does it rely to ?
Best Regards,
Ed
