Dovecot, Postfix and Dovecot LDA (LMTP) delivery
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,

How "safe" is reject_unknown_helo_hostname?
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,

postfix and spam, I am impressed
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

Postfix restrictions
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

Using Dovecot-auth to return error code 450 (or other 4xx) to Postfix when user is on vacation
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

Catch-all with LMTP and Postfix
Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP. I would like *@example.com (everything) to go to virtual at example.com, where virtual is a valid virtual user. It seems that things are getting as far as LMTP, but then the mail gets bounced. To wit: Aug 21 08:02:50 hostname postfix/lmtp[4914]: 8DF8E9AFE6: to=<test at example.com>,

Trying to get DSpam+Dovecot working with Postfix and local/virtual domains
Hi, I'm hoping that someone might be able to help, as I've been going in circles with trying to get the right configuration done here. I'm also not sure whether this is more of a Dovecot or DSpam question, so I'm posting the same to both mailing lists. My goal is to have a mail setup that is as follows: [Incoming email] --> [Postfix] --> [Amavis] --> [DSpam] -->

Helo Checks not always working?
All i have is : smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated   I disabled the unknown restriction due to lots of customers of me are missing PTR records, which needs to be set bij the internet provider. So they got blocked, i had to remove these.   The Helo check is often on the IT department can adjust them selfs. And most spammers have incorrect helo’s
