When I send email via my Postfix, the header actually contains the IP
address of my laptop. Such as 192.168.1.113 [12.34.56.78]) in the

I am using body checks as a very simple spam filter. It catches most of
the marketing emails, with no false positives (so far):
If a message is rejected, I can see it in my logs, i.e.:
message content rejected
But I am wondering what would happen, if a false positive occurs. in
that case, I

Hello,
I have noticed that my Postfix never resolves client IP Addresses into
hostnames. In the logs I have always entries like the following:
connect from unknown[173.194.40.54]
I can resolve the IP manually into FQDN, using dig or host commands:
host 173.194.40.54
So any DNS

You need the correct DNS server in /etc/resolv.conf.
You must not have disable_dns_lookups=yes in main.cf or master.cf.
You must not have

Hello,
I am using Postfix with Maildir format, where user's mail is delivered
to $HOME/mail/Inbox and the home is mounted from NFS.
It happened to me that NFS was down (or simply unmounted),
$HOME/mail/Inbox did not exist, and new mail could not be delivered. I

Hello,
I am wondering why the default error limits in Postfix are set so high:
smtpd_soft_error_limit (default: 10)
smtpd_hard_error_limit (default: 20)
I have changed them to 3 and ${stress?1}${stress:5} respectively,
and my servers is still being flooded with relay access denied.

Hello,
I am using postfix with maildir format. The filenames of messages stored
in maildir look something like this:
1402593073.Vfe00I75441M583245.alpha:2,S
where
the filename is subdivided into three pieces, separated with dots:
time.delivery_identifier.hostname
As I see it, the whole
13 matches
Mail list logo
