Hi all, Just out of curiosity: is there anything we can do, on the samba side, to counter the recent ransomware attacks? (or limit the damage done) I'm thinking like: limit the number of files per second a client (workstation) is allowed to edit, or some other smart tricks..? It would be nice if samba could be an extra layer of defense. Something perhaps a vfs module could help with..?

Hello people, I am using now qmail in cluster with LDAP + Interscan Messaging Security Suite from Trendmicro. I need to develop a new solution with: - postfix - dovecot - anti-spam - anti-malware. I am thankful any help or suggestion for anti-spam and anti-malware. Thanks in advance! -- :) cumprimentos ---------------------- Jos? Lu?s Faria Network Eng./Administrador de

I have had the same email address since 1997 (when microsoft stole bob.com from me thanks to network solutions...) In the early days I of course was free with my email and used it everwhere. Fast forward to 2012, some 15 years later. woof..the amount of spam sent to me has always just kept getting worse and worse. On my centos 5 server I just used sendmail with spamassassin and it killed a

Running CentOS 4.2 with all updates. I've been using sendmail for my MTA since forever. I've grown used to it and I can make it do what I want it to. However (there's always a catch, isn't there)... Lately it seems that some mail is being lost. I've noticed some instances when a message was sent to myself and others which I will only see if someone replies back to

Helo hostname MUST have resolvable hostname. Crazy or not, but i use this. The _access-allow parts for server you really trust. smtpd_client_restrictions = permit_mynetworks, reject_unauth_destination, check_client_access cidr:/etc/postfix/check_client_access-allow.cidr, reject_unknown_hostname, reject_non_fqdn_hostname, reject_invalid_hostname,

Hello to all members. I am using Dovecot for 5 years, but this is my first post here. I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters). I have an issue with auto-replies - it is vulnerable to spamming with forged email address. Forging can be prevented with several Postfix settings, which I did in the past - but was forced

Hi, I'm currently fine-tuning my mail server (Postfix and Dovecot on CentOS 7). SPF, DKIM and DMARC work fine, now I'd like to limit the spam tsunami. Besides the official Postfix documentation, I've read a few articles about Postfix spam restrictions, namely these : https://www.linuxbabe.com/mail-server/block-email-spam-postfix https://wiki.centos.org/HowTos/postfix_restrictions

Hai, Not really a question for samba technical, but i can share this. No need for setting things on samba, that wont help a lot. Below is my setup and its just how you configure your pc's. This and almost all other "malware" is EASY to block, but it wil have impact on how your work. First, start with NEVER work/run as user with administrator rights. If one needs it, then not

Hi, I'm really struggling with the following inbound filtering: Let's say:? My email address is "my.email at example.com" ? I've setup a filtered address "filtered.email at example.com" ?

The server receives

Hi, I am going further with dovecot configuration. Finally managed to configure roundcube 0.3 with managesieve plugin. And it works, although... not perfectly :( For some issues probably roundcube-managesieve is guilty, but simply the sieve plugins seems to work wrong.
