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

Hi, I'm running our local school's mail server on CentOS 7, Postfix and Dovecot. We get quite a lot of spam, so I have the following sender restrictions in my /etc/postfix/main.cf: --8<------------------------------------------------------ # Restrictions SMTP smtpd_helo_restrictions = reject_unknown_helo_hostname smtpd_sender_restrictions = reject_unknown_sender_domain,

I wanted to pass this along. I'm sure it may be nothing new to most of you, but it has greatly reduced sasl attacks and spam. I found most of it here: https://scottlinux.com/2011/05/26/prevent-postfix-brute-force/ I added the fail2ban rule and modified my postfix main.cf as follows: smtpd_client_connection_rate_limit = 3 smtpd_delay_reject = yes smtpd_helo_required = yes

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

I'm trying to configure mail forwarding through Gmail on CentOS 6 with postfix, following the blog http://carlton.oriley.net/blog/?p=31 and I think the blog has missed the step: # postmap /etc/postfix/sasl_passwd - as I've seen in the /var/log/maillog: postfix/smtp[1926]: fatal: open database /etc/postfix/sasl_passwd.db: No such file or directory postfix/master[1831]: warning: process

Hi list, I am running a Debian Lenny machine with Postfix 2.5.5 and Dovecot 2.0.8. Up until now I ran Postfix with the Procmail delivery agent succesfully. The machine has only local users; I am not using virtual mailboxes. Due to obvious reasons I want to switch to Dovecot LDA delivery, through LMTP. I spend quite some time finding 'the' configuration for both Postfix and Dovecot,

Dear All While setting up postfix, at one point I need to do postmap /etc/postfix/transport But I get the output as *bash: postmap: command not found* I was just wondering is it something I need to install separately. Thanks Austin

Hi list, I have noted over the last week or so my DNS servers are dumping lots of messages for bogus domain lookups. Examining the postfix queue with postqueue -p: I see many (Host or domain name not found. Name service error for name=bdgiedjhea.po6e4ina.com type=MX: Host not found, try again) Jake at bdgiedjhea.po6e4ina.com My question - why does this

hey friends, I am trying to make postfix run with tls in chroot mode, but I am not able to send the messages with tls on. I am using postfix 2.2.10 on centos 4.0 and I had compiled the postfix from sources with tls & cyrus-sasl support. I copied the certificates from /usr/share/ssl to /etc/postfix. Below are the errors I am getting: May 25 13:27:51 test1 postfix/smtpd[4095]: warning: TLS

http://hg.dovecot.org/dovecot-2.1/rev/f562bcaca215 implements "postmap" type sockets, which follow Postfix's tcp_table(5) protocol. So you can ask: get user at domain and Dovecot answers one of: - 200 1 - 500 User not found - 400 Internal failure So you can use this with Postfix: virtual_mailbox_maps = tcp:127.0.0.1:1234 With Dovecot you can enable it with: service auth

As I understand it, SMTPUTF8 uses a UTF8 namespace. So, this would indicate SMTPUTF8 # postmap -q

Hi all I am unsure if dovecot files like userdb and passwd also need to be postmap'd i.e. postmap userdb or userdb passwd when I use the typical data format for creating userdp postmap outputs the error > postmap userdb postmap:
