Hello,
I have been using the following config without problems, but after I
added the domain: hesperia-space.eu, mail to the new domain becomes
undelivered with the error (example from one attempt to send mail):
Feb 17 15:21:38 mailgw3 postfix/smtpd[17664]: NOQUEUE: reject: RCPT from

Hi all!
I'm using Debian GNU/Linux Jessie 8.7 with Postfix 2.11.3-1.
I would like to know what you think of the security settings suggested
here [1] for Postfix.
I have tested it against this [2] site, but it seems that fails to
discard other ciphers; on "Weak ciphers" I get "supported
RSA_WITH_
Hi,
Here is how I am dealing with "weak ciphers"
You may be able to do the same type of config ?
In /etc/postfix/main.cf
# -ALF 2016-09-07
# disable RC4 ciphers with TLS connections.
#smtpd_tls_exclude_ciphers = RC4, aNULL
# -ALF 2017-01-09
# disable weak ciphers, and RC4 ciphers

Hai,
It all depends all in what you need and want.

Which i simply dont allow anymore. ( The sslv2/v3 )

You need to run postmap on a hashed map for it to take effect

I am running postfix 3.1.0 on an xubuntu 16.04 system and postfix 2.9.6
on a Raspberry Pi running Debian.
They seem to act very differently as regards the use of ports 465 and
587 and I'd like things clarified so I can understand better.
I use both postfix installations to send outgoing E-Mail (i

Submission or SMTPS
I'm no expert either, just curious what your setup is.

He is SENDING outbound mail to his upstream, not listening for incoming mail.
As for the original post, 587 is the right port to use anyway, so ignore your
