Quota, maildir, MySQL,
Hi everybody,
I am trying to work with quota. I use postfix and dovecot with a sql
backend. Below you'll find my configuration. Everything works except for
the quota part. It doesn't seem to see the quota and doesn't respond to
the sender that the client is over its quota.
versions:
postfix-2.5.20070531-mysql

Thanks for the help in advance.

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

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

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.

postfix tightening
I am used to sendmail and am using Postfix now and am uncertain of some
features. I typically would comment out the line in sendmail.mc that
went something like 'accept unresolvable domains'
I tried using
smtpd_sender_restrictions =
reject_unverified_sender
reject_unverified_smtp
and this seems a bit too restrictive and got some bounces on legitimate
senders
so I'm

stat failed: Not a directory
I have recently installed dovecot on a FreeBSD mailserver running postfix.
But when I try to login with imap/pop3, I always get an error "stat failed:
Not a directory".
I guess it is something wrong with the mail format postfix uses to store the
message, but I don't seem to find the correct solution.
Here's the postfix log with the successful delivery:

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.

reject_unauth_destination,
check_client_access cidr:/etc/postfix/check_client_access-allow.cidr,

SASL attacks and SPAM
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_delay_reject = yes
smtpd_helo_required = yes
