greetings,
Do you know why many providers even those big ones didn't implement SRS when
forwarding email to other ESP?
for instance, outlook.com, mail.ru, and even google domains who has specificed
email forwarding feature for their domain users, don't have SRS enabled in
their forwarded messa
t-online has no SPF & DMARC & DKIM settings. but google try to maintain a
reliable sender IP list for them.
if you forward a message which is original from t-online to gmail, if you don't
have SRS enabled for this forwarding, gmail will just reject it.
as far as I know, many ISP level forwardin
One way is webmail I may think.

I was once charter's customer.
But I leave them since charter was bought by Spectrum.
And spectrum blocks all IP from DO and Linode.

Hello,
My mailserver once had some issues on sending messages to different providers.
I have contacted the provders and most of them were kind enough to resolve the
blocking issue. Thanks for them (ATT, GMX, 1and1 etc).
But t-online.de keep blocking me. I have contacted them twice and got the s
I have postfix with opendkim and policyd-spf enabled.
when a message incomes they do check SPF and DKIM (for which I can
verify the results in messages header).
I don't know how to configure postfix to take actions on these failed
messages, such as reject them.
Thank you

Hello list,
As a receiver MTA (postfix), if DKIM, SPF or DMARC has got failed to the
sender domain, what action postfix will take for this incoming message?
reject or greylist it?
I have setup the mail system (as this domain openmbox.net) but not sure
about it. thanks.

When using Postfix "smtpd_tls_security_level = encrypt" in main.cf is it
possible to make an exception for an incoming mail server connection that does
not support encryption?
Thank you
Henry
Asking user to type in “_submission._tcp” seems like a poor workaround. This
being Autodiscovery it’d be logical for Postfix to automagically derive SRV
lookup address based on relayhost setting.
“relayhost = example.com” is an obvious candidate for SRV autodiscovery if an
MX lookup fails or if

I am not 100% sure however I suspect my email server has been compromised.
I am using Kolab.
I previously only logged inbound connections to my fw however I have
just tested logging outbound connections and I see multiple repeated
connections to a a few IPs on port 25.
The prime contender is 69.

As each user has an individual "Spam" email folder I would like spam
emails to be moved to the individual user's spam folder instead where
the individual user can then review them.
/var/spool/imap/domain/m/mydomain.com/h
When reading through main.cf and configuring postfix I am unsure of
which domain, origin and hostname values to use.
For example say our public domain is mydomain.com and we have a
certificate for mail.mydomain.com and our MX points to
mail.mydomain.com
Our mail server called hermes runs our our

thanks Viktor. this is what I was ultimately trying to achieve:

When I send a message to Gmail I am informed that it could not be
authenticated and will probably end in the spam folder. I understand
the resolution to this is to obtain an SSL certificate and configure
postfix to use that certificate.
I have obtained a certificate from LetsEncrypt which is worki

I have created a policy service, which checks quota, returning 'reject' if
the mailbox is full, and 'dunno' otherwise.
smtpd_(data|recipient)_restrictions =

And it's all working fine.
However, I only want that policy to trigger for incoming mail - m

Thank-you, for the explanation and t
I have defined a few custom smtp transports to limit deliveries to
certain large domains such as Yahoo and Hotmail. These are applied via
the transport map file to match recipient address domains.
There are a large number of recipients I would like to use a custom
transport for, but whose actual
