#171420 — Getting fqdn, postfix, Comcast to all play nice together

[Multipart message — attachments visible in raw view] — view raw

I have the following issue (seems to be common although my details seem to
differ):

1. I recently registered a new domain as WWW.whatever.org or whatever.

2. Postfix gets installed.

3. "Internet site " is enabled fqdn added.

4. Email cannot be sent out to my Gmail address since it magically "times
out" when contacting the servers (even though telnetting to mine and
Gmail's works fine at port 25)

5. In theory thus should mean that they aren't blocking 25, and it should
work.

6. In the core wiki for Postfix I have the MX record of my server updated
from the registrar to mail.whatever.org (pita since it's dynamic and not
static).

7. I want to avoid using gmail's smtp and comcast's servers since I'd love
to host this on my own.

How can this be accomplished in Debian (not Ubuntu, or something else)? (I
get irritated at Ubuntu specific explanations {which usually don't work}
getting all the search results)

Any help would be appreciated as I spent ~3 days of work and wiping the
entire OS in case I went wrong somewhere.

Gmail doesn't block port 25 but they do refuse all non-secured attempts to
connect.

So how do you dynamically specify getting a connection to be secured or
not. If it's only Gmail, why van I telnet to their port and get their mail
server?

Seems counterintuitive.

Were you expecting Gmail to be either intuitive or logical?? :-o

Please use example.com when you do not want to disclose your real domain
name. The domain whatever.org does not belong to you.

You will not be happy with such a setup.

For receiving mails, you would have to update the MX record for your
domain whenever your IP address changes. And you always risk losing mail
to random strangers who happen to use any of your old IP addresses.

For sending e-mails you will notice that *a lot* of receiving systems
will refuse talking to systems on dynamic IP addresses. Also, you can
only expect to send mails from your mail server using e-mail addresses
in your own domain. If you try to deliver an e-mail with a gmail sender
address to gmail's servers, gmail will treat it as spam. The same
probably holds for most other major e-mail providers.

Then do what I do: rent a small VPS with a static IP address and run
Postfix there. You can configure Postfix to deliver mails of senders
from its own domain directly and use an appropriate relay host for
specific senders / sender domains.

There's really no better way than spending even more time (and some
money). Read the Postfix documentation. Postfix will not do what you
want it to do unless you understats its configuration files.

I like that. I'm worried about one of the requirements here (under "Things
you will need"):

"

   - A  permanent *internet connection *and an* IP address* for your mail
   server that does not change. The IP address should *not be blacklisted* on
   the internet. Check the IP address at web sites like
   http://www.anti-abuse.org/multi-rbl-check/ or http://rbl-check.org/. If
   your IP address shows up on black lists then other mail servers on the
   internet will likely refuse your emails or consider them spam."

Out of curiosity I ran against the second website and tried to see if the
present IP the router has has an issue. So far only two marginal servers
have an issue with the current one out of what looks like (about) dozens.
I'm currently on a "free" year trial of Amazon EC2 from AWS. I was
concerned about the costs. Compared to others. It looks like this could be
done for under 15.00 USD for a cost. Any thoughts for or against Amazon?

Please don't top post on this list, it breaks up the flow of the thread for
people who read the thread after it's finished. The primary purpose of the
list is to get your questions answered, but the secondary purpose is to
help those who come after, and top posting impedes that.

Anyway, I'm a fairly heavy Amazon web services user, using multiple
Workspaces instances (remote desktops), EC2 instances (servers), RDS
instances (database, in my case MySQL), and Elastic Beanstalk (self-scaling
web site). I find it performant and highly reliable. I can't vouch for the
tech support as I haven't really had to use them. They have a user forum
which is not terrible but not great. The documentation can be a bit
frustrating but if you are willing to devote the time to wading through the
adverto-babble the information is there.

All that sets me back about $250 a month. No doubt not the cheapest but you
have to decide if what you want is cheap or good -- you don't typically get
both, except sometimes temporarily by luck.

So I need to reply to the comment block in this manner then to avoid that?
I've not heard much about that term, and it's been a while that I've used
mailing lists. I can understand however, if that's the case.

you could access from ec2 but entirely separate and used for
desktop/non-server use? If so that would be theoretically awesome for some
interesting cases. It could help me not to have to pony up the dough to
Microsoft et all directly for a piece of software I may not use all the
time, not to mention doing interesting interactive things.

Beanstalk sounds interesting as well but almost overlapping ec2, almost
like ec2 on demand just for apache I would guess.

Nice, but I guess you must get some sort of residual income from that
otherwise it wouldn't be important? Good to know that would show a real
world use case to give me an idea.

from what i have read in the past it's comcast(cable providers in general) that have their ports closed for people trying to run mail servers on home accounts, business accounts can have them.

you could try to have your dynamic hostname provider send your incoming mail to a different port and then just configure your postfix to listen there.  this might also work for your outgoing, yet not sure.

check with comcast blocking what ports.  sometimes they will block 80(http) also.

good luck.

I have been able to create websites, and am able to use the fqdn to show up
my web page I have hosed on the server. I just have to have ddclient update
the ip address with the dns settings. I just have the box NATed behind the
router.
