MandrillApp integration

  Hi Friends!

I'm posting to this list because I'm facing an issue when integrating 
mandrillapp on exim.
To the point: When I exclude some domain from sending via mandrill, 
messages can't be sent.

My router:

# /etc/exim.conf.local
# cPanel server
=================================
 <at> PREROUTERS <at> 
send_via_mandrill:
driver = manualroute
domains = ! +local_domains
senders = ! * <at> domain.tld
ignore_target_hosts = 127.0.0.0/8
transport = mandrill_smtp
route_list = * smtp.mandrillapp.com
no_more
=================================

When I set "senders" to exclude "domain.tld" from sending via mandrill 
(sending locally), I got this:

=================================
2015-04-27 19:43:13 1Ymrk9-000zDR-7K <= email <at> domain.tld H=localhost 
(domain.tld) [::1]:50354 I=[::1]:25 P=esmtpa 
A=dovecot_login:email <at> domain.tld S=508

Controlling Backscatter

A quick summary of our setup.

We accept mail for customers, filter the mail and then forward it on to
their server.

To prevent backscatter we do not accept any mail for an email address that
does not exist at a domain.

A problem we run into however is if our customers servers (where we deliver
their mail) has spam protection (a 2nd level, which we do not recommend)
they may reject the mail.  We often see stuff like this, when trying to
deliver to the customer server:

550 5.7.1 Message rejected as spam by Content Filtering.

We have no way to know if the destination server will accept the message
when we accept it on their behalf.

We trap those errors (delivery failures we call them) and report them to
the users.  Our Exim server handles the undelivered and sends a bounce back
to the original sender.

If it is a problem like a full mailbox, temporary error etc. etc. we want
to send back an undelivered notice.  In the case where our customer is
rejecting the messages because of some spam block we would rather not send
back any undelivered notice.

Essentially we want to control what undelivered notices we actually send.
Any way to do this?  Selectively choose what undelivered notices to send
back to the original sender?

how exim parses multiple headers into variables

Hi,

I have an interesting behavior of exim on Debian regarding multiply
existing headers - but it also may be something really stupid.

This is my exim:

Eximfilterfile with UTF-8 support for subjects ?

Hi guys,

just a quick reinsurance, exim can filter by subjects or emails, if the
subject is encoded in utf-8 ?Q? format, correct ?

Subjects like this:  =?ISO-8859-1?Q?Crypto_plugin_f=FCr_dovecot?=  or
even better in base64 encoded utf8

best regards,
Marius

Changing email headers to reflect server IP when they pass through Exim

Thank you Phillip and Chris. I will look into both your respective 
solutions and provide feedback.

Thank you both,

Re: Changing email headers to reflect server IP when they, pass through Exim

That's actually a very interesting idea and I might try it myself. 
However it's not a practical solution for the issue I have. The reason I 
say that is because there are a few hundred users who send mail through 
this server and the vast majority of them aren't tech savvy enough to 
set something like this up themselves and unfortunately I cannot go hand 
to hand and manually set this up. Beyond that the only users who have 
issues are the mobile users. Most businesses have a clean static IP in 
office, but their mobile devices aren't so lucky.

I really appreciate the inventiveness of your response and how 
articulately you explained it, but unfortunately it won't solve the 
particular issue I'm having.

I'm honestly hoping there was a way to dynamically rewrite IP address in 
the email header to reflect the server it's being sent from. That would 
solve the issue completely.

Thanks again,

Internationalized email

Support has recently been added in the Exim development tree
for UTF-8 in email envelopes.  It has not hit a released
Exim version yet.

For the technical, this is the SMTPUTF8 extension defined
in RFC 6530 et. al.

Details are in the experimental.txt documentation.

People interested in trying this in a production environment
will need to compile from source, with EXPERIMENTAL_INTERNATIONAL
defined.  Feedback would be very welcome as the systems I
can run it on are unlikely to see much internationalized
traffic.

The Exim sources are available from
  git://git.exim.org/exim.git

The bug for SMTPUTF8 specifically is
  http://bugs.exim.org/show_bug.cgi?id=1516

and the umbrella bug for internationalization is
  http://bugs.exim.org/show_bug.cgi?id=1177

[OT] ProtonMail

So today I have come across ProtonMail -  https://protonmail.ch/ - and
given the security features, I couldn't help but bring to the discussion
here, especially because I noticed a name that rang a bell in my mind! One
of the contributors, Mike Cardwell, is a major contributor to this list.

Many organizations and individuals I am sure would really appreciate a
secure mail system that would ensure their 'enemies' do not get to snoop on
their businesses.

RotonMail offers encrypted email. That's great, but left me confused
totally, given that no private/public keys are involved.

But what left me completely lost - Self Destructing Messages
With ProtonMail, emails are no longer permanent. You can set an optional
expiration time on ProtonMail's encrypted emails, so they will be
automatically deleted from the recipient's inbox once they have expired.
This works for both emails sent to other ProtonMail users, and encrypted
emails sent to outside email addresses. Similar to SnapChat, we've added a
way for you to have even more ephemeral communication.

Okay, I have been like dreaming, because it's hard to imagine all this:)

A (blacklisted) dynamic IP-address in a Received header line is normal.
Most honest users worldwide are in this situation.
IP-address of your server is searched in blacklists,
not IP-addresses from every Received line in the header.
Please give an example of full unredacted header and the
error message your user got while trying to send that message.
Also, check your server in http://valli.org
