Hi Randy, |

I would give the package 'mail-filter/policyd-weight' a try to stop this |
4 |
unwanted mails. |
5 |
|
6 |
But keep in mind to have some 'check_sender_access' and |
7 |
'check_recipient_access' files on hand to bypass the fail-positives |
8 |
senders and recipients. |
9 |
|
10 |
Example: |
11 |
# postconf | grep 'smtpd_recipient_restrictions' |
12 |
smtpd_recipient_restrictions = permit_mynetworks, check_sender_access |
13 |
hash:/etc/postfix/sender_checks, check_recipient_access |
14 |
hash:/etc/postfix/recipient_checks, check_policy_service |
15 |
inet:127.0.0.1:12525, warn_if_reject reject_unknown_sender_domain, |
16 |
warn_if_reject reject_non_fqdn_sender, warn_if_reject |
17 |
reject_unknown_recipient_domain, warn_if_reject |
18 |
reject_non_fqdn_recipient, warn_if_reject reject_unauth_pipelining, |
19 |
warn_if_reject reject_unauth_destination, permit_auth_destination, |
20 |
reject |
21 |

I am getting a huge number of connections to my mail server (postfix) |
33 |
compared to usual. I've seen as many as 50 connections open at one |
34 |
time. The logs show that the connections are from several computers of |
35 |
varying IPs, and they are all trying to send mail to random mailboxes on |
36 |
my domain. It's very annoying, and I have noticed that inbound mail |
37 |
seems to be lagging by several hours. Is there something similar to |
38 |
denyhosts for spammers? Any other suggestions? |
