I thought I'd post the contents of my master.cf file as well (for
completeness):
smtp inet n - n - 1 postscreen
smtpd pass - - n - - smtpd
dnsblog unix - - n - 0 dnsblog
tlsproxy unix -
Thanks Viktor. I have set it to:
smtpd_tls_exclude_ciphers = LOW, EXPORT, MD5
How does the rest of the config look? Secure? Any silly mistakes?

Hi All
After building my new Postfix server I spent days securing it as best I
could. So far it seems to be running fine but I was wondering if someone
would mind having a look at my main.cf file to see if there are any
"holes"/issues in the config. I'm particularly interested to hear what

I doubt it as mail is flowing and RBL lookups are working fine.

Fair enough. Thanks Wietse.
I have done plenty of research online regarding this but still haven't had
much luck. I will contact the developer.
Thanks everyone for the assistance.

When you install the policyd-spf port on FreeBSD it installs all the

Thanks Scott.
If you look at my previous post you can see that I have installed
postfix-policyd-spf-python but am having DNS timeout issues when I enable
it. I have been looking online for a solition but have come up empty handed
so far!

Thanks for the help. I have installed the postfix-policyd-spf-python port on
my FreeBSD server and enabled it in the main.cf and master.cf config files
as follows:
smtpd_recipient_restrictions = check_policy_service
unix:private/policyd-spf
policyd-spf unix - n n - 0 spawn

Hello
I have an SPF record created in DNS for my domain. In my main.cf config file
for Postfix I have the following SPF settings:
spf_received_header = yes
spf_mark_only = no
smtpd_recipient_restrictions = peject_spf_invalid_sender,
permit_spf_valid

Yesterday I had my SSL certificate re-issued. I now have two

Also, why is it when I send an email from my mobile phone its instant? In the

Just trying to understand this.

Yes, you are correct. That is the cause of the problem. A quick entry of my
machine in the hosts file sorted that one out!
I'm just baffled why I have never experienced this issue before.
Thank you everyone.

I've been running fine for about 3 hours since removing -D and removing zlib

I will check the logs again tomorrow morning to see how things look.
