all postfix mail forwarding rejected by my gmail account
I've been using postfix on a digitalocean droplet for years to forward mail from several domains on that server to my gmail address.
Now they're all being blocked by google, with this message:
Our system has detected that this message is 550-5.7.1 likely
suspicious due to the very low reputation of the sending IP
running postfix 2.11. Can't upgrade that either; apparently ubuntu refuses to recognize postfix 3.
Can anyone help? I have no idea which way to turn.
How can I securely forward emails directed to my domains without running into this problem?

Modifying mydestination directive in postfix MTA
I'm not good in English and I cannot understand what does this mean:
I've followed the first code block of image above and my current configuration looks like this:
. . . mydestination = $myhostname, lamtakam.com, Ubuntu-1604-xenial-64-minimal, localhost.localdomain, , localhost . . .
What change should I make now?
lamtakam.comis the same as

Fetchmail Postfix Dovecot - Mail not handed over to Postfix
I am trying to setup my new email server and ran into a wall and I cannot find any instruction online that helps me overcome my issue. That's why I hope for your support.
I do not have a FQDN and do not want one, just to get this point out of the way. To setup the email infrastructure I mostly followed the instructions from https://workaround.org/ispmail/stretch. In addition I installed fetchmail to pick up my emails at my provider. I tested that with the following options:
poll pop.mail.yahoo.com with protocol POP3: user "MYUSERNAME", password "MYPASSWD", is USER here option ssl
With these options I ran
fetchmail -v -d0 -f /etc/default/fetchmailand the result showed that my email was picked up. Now one of my issues is that I do not have a user on my system that is called USER as specified in the fetchmail filed above. I want to use virtual users as it allows me to be much more flexible. But whatever I did Postfix did not want to process the email for "USER@localhost". I added the domain "localhost" to my SQL domain table, added the email "USER@localhost" to my virtual users table... nothing. Receiving and processing this email was always rejected by postfix. The error message is
fetchmail: SMTP listener doesn't like recipient address `USER@localhost'
Then I thought I go the route of multidrop mailboxes and specify the MDA in the fetchmail poll request. Goal was to hand over the polled emails to postfix, where they would have been processed and handed over to dovecot, which I want to use as the Mail Delivery Agent. And that is where I am stuck. I cannot figure out how to properly define the poll request with this MDA option.
So, long story short, what I want to achieve is to fetch my emails, hand them over to postfix to process and then store them in the virtual mailboxes using dovecot.
I am aware that this topic is not solved with one or two answers. If you could patient with me solving my issues I would be more that grateful.
Some more details on my config: main.cf
myhostname = Mailserver.xyz mydestination = $myhostname, Mailserver, localhost.localdomain, , localhost virtual_transport = lmtp:unix:private/dovecot-lmtp
The lines show myhostname, my destination and the virtual_transport that I set up. The virtual transport ensures Postfix hands stuff over to Dovceot, so Dovecot can be used as MDA.
My virtual mailbox domain table contains 2 columns, id and name, and they contain the localhost as domain. My virtual mailbox maps contain 5 columns, id, domain id, email address and password. Password is irrelevant for now but it will be uses to login to dovecot through the MUA. The table contains my USER@localhost which should allow receiving emails as specified in my first code section 'poll pop.mail.yahoo.com with protocol POP3: user "MYUSERNAME", password "MYPASSWD", is USER here'.
Anyway that is all I can think of right now. Please let me know what other information you might need to help me out. If you could point me into the right direction, that would be highly appreciated.
Hide SMTP server IP
I am running postfix 3.2.5 on my Linux computer. Using this SMTP server (running on localhost) and a python script I wrote, I am able to send emails to the outside world.
As you can see the IP adress of my mail server is visible. The problem is that it is also the IP of my computer.
I was wondering if I could hide the IP of my computer sending mails through a proxy or something like that.
Is that possible ?
Looking for e-mail forwarding service (Mailgun is not an option)
I'm looking for serious e-mail forwarding service (custom domain -> gmail).
At this moment I started integrating Mailgun service but many problems occurs. Automation is impossible because Mailgun disables my domains preventively - that results messages are not delivered.
Now my account was disabled, also preventively and I can't do anything (just waiting for support - more than two hours and still waiting) - this is not acceptable and I can't provide my service based on Mailgun afraid that the customer will not receive any message sent to his domain in the future.
After testing Mailgun i dont believe in services like SendGrid or Mailjet but maybe I will?
API is required, service must be available for non-manual management. Any alternatives for premium purposes?
Forward every other email in Outlook 2013
Looking for some kind of script or code to run to forward every other incoming email that comes from a specific email address to a certain person.
In other words, I get emails from email@example.com, and every other email needs to be forwarded to Dave, and every other email needs to be forwarded to Sally.
Alternatively, would it be easier to find a way to alternately color code every other email in both Dave and Sally's Outlook programs, then assign them each a color to be responsible for?
Inbound/outbound email forwarding solution through Gmail with DKIM
I used to run my own email server but understood emails have to be managed by an external provider. I use
firstname.lastname@example.org my primary address for years. To manage spams, storage, webmail and others features, I chose Gmail with the address
What I want:
email@example.com the address I give to websites/people, it looks nice and I want to be able to switch from Gmail in the future
- instantly receive (push notification) all the emails sent to
*@lastname.cominto my Gmail inbox (I own
- send emails as
firstname.lastname@example.org Gmail (I only want people see my primary address)
- people receive valid DKIM-signed and encrypted (TLS) emails from
What I don't need:
- easily send emails from any address of
firstnameis enough (but it could be cool)
- setup my devices with
email@example.com, using Gmail is much better (mostly for push notification)
I'm ready to send few hours to develop my own small solution with a SMTP library or others.
What is the best solution for my needs?
