It may take more than one step to fix this issue Take the step mentioned earlier. Log into your google email account and then go to this link: https://www.google.com/settings/security/lesssecureapps and set "Access for less secure apps" to ON. Test to see if your issue is resolved. If it isn't resolved, as it wasn't for me, continue to Step #2. Go to ...

Once DKIM was setup (for help, see this guide) and verified successfully on my domain I still had to enable it in the AWS console at SES -> Domains -> DKIM Once that was done mails to Gmail no longer show up with the via bounces address. You can see it still shows as mailed by: amazonses.com when you view details of the sender but that's OK ...

There is one really good reason to disallow this: Even if you configure gmail to use the company address as the FROM-header, gmail will still add a Sender: <google-alias@gmail.com> To every mail that is sent out. Now, this might seem like a small issue, was it not for Outlook that displays a Mail with these headers: From: ...

This is called a "catch all" Mapping is done using /etc/postfix/virtual file. vi /etc/postfix/virtual Append code as follows, replacing domain and emailusername with actual values: @yourdomain.com emailusername Save and close the file. Run following command: postmap /etc/postfix/virtual Also make sure you have following line in /etc/postfix/main.cf ...

While I haven't tried to relay through a provider using the submission port (587) it should be possible. To enable Postfix to relay you'll need to setup a file with the authenticated credentials to use and make some modifications to your /etc/postfix/main.cf config file. The first is the authentication credentials. For this I simply use ...

Google has a corporate solution called Google Apps. Your company could consider using that. The paid version of Google Apps has service level guarantees, which could be better than what your internal IT could provide. As for advantages, Google has better spam filtering than most other email providers, because they have so much mail data they process ...

One feature you may find your missing is Outlook. Yes you can use Outlook with Gmail, but not to the same level. You can't use Outlook to open other users calendars or mailboxes, accept meeting invites or get the same offline functionality. To get the full functionality of Gmail, you have to be using the web interface, which some user won't like. You ...

The delay appears to be within google's network. However, this is technically not a problem. SMTP delivery is not and should never be viewed as an instant method of communication. It's a store and forward with multiple stops along the way which means multiple queues and multiple locations where delays might occur. SMTP is designed this way and delays can ...

Along with verifying the domain and enabling DKIM on the domain, I also had to enable DKIM on the verified email address I was sending from.

Your message is being rejected as spam because it precisely matches the profile of a very common malware distribution scheme: messages claiming to be order or shipping confirmations, with PDF attachments. My suggestions: Clean up the grammar. "This is purchase order document for purchase order #1001"? Broken English sounds incredibly spammy, and although ...

Simple answer: don't have a catch-all on your domain. In fact, don't accept mail on your server for accounts that don't exist, full stop. Just reject it outright, during the initial SMTP transaction. This is especially important when you have a front-end SMTP "proxy" server that does things like anti-virus, anti-spam etc, before passing clean(er) emails to ...

You probably want something like this. (see link) IN MX 1 ASPMX.L.GOOGLE.COM. IN MX 5 ALT1.ASPMX.L.GOOGLE.COM. IN MX 5 ALT2.ASPMX.L.GOOGLE.COM. IN MX 10 ASPMX2.GOOGLEMAIL.COM. IN MX 10 ASPMX3.GOOGLEMAIL.COM. IN MX 10 ASPMX4.GOOGLEMAIL.COM. IN MX 10 ASPMX5.GOOGLEMAIL.COM. Make sure you add that trailing period.

I did the same thing recently for two of my clients. Commander Keen is correct you are looking for Google Applications. There is a free and paid plan. The paid plan has more uptime guarantees and vastly more space. You route mail from your server to Google by modifying your Zone Record/DNS. Its not that hard to do. And they provide some decent ...

I think from a security perspective, you should not allow this. All the data in the company mail system belongs to the company, I think you'll be putting the company at risk this way by opening this up - as usual - security comes at the cost of convenience, there's no easy way around it. Of course you can't go too far with restricting people's freedom with ...

I considered making this switch at a private school I volunteer with. We decided to stick with Exchange for the following reasons: 1) End user re-training, they like Outlook alot. 2) Being able to find people in the directory of Outlook, I tried to find a way to re-produce this with Google Apps but I could not find one. Our users don't want to have to ...

Mailchimp have an excellent article on How To Avoid Spam Filters Update: Ok, seeing as I got slammed for just giving this link (to be fair its contents probably wouldn't solve your problem here), I've added more specific to what you're sending. I suspect its the text you're using. 'Please confirm your email address by clicking the link' - I think you ...

You want to prevent this sort of thing in the future? Use a real MTA instead of Google Apps. As you've discovered, it is certainly possible to relay emails through a GApps account, but it's far from ideal, and frankly, it's not what that service was built to do. They give you zero visibility into logs of any sort, which you'd need in order to troubleshoot ...

Well it is not the one liner I wanted, but this is how to fetch and import a certificate from scratch: # Create a certificate directory ~]$ mkdir certs # Create a new database in the certs dir ~]$ certutil -N -d certs # Need now a chain certificate - May 18, 2015 ~]$ wget ...

Disclaimer: This answer was speculation one until GMail person confirmed it. Looks like it's GMail mishandle your fetched email here. Some peoples also report similar case with yours in here, here or here The problem is: GMail also deploying SPF measure when scanning email after fetching it via POP3. Normally SPF-checking take place in SMTP transaction ...

I discovered that the problem was that although we had SPF records set up for our domains, we did not have a DKIM record associated with our domain. In order to add a DKIM record in Google Apps, you need to do the following: Go to the Admin Console Click on "Google Apps" Click on "Gmail" Scroll down until you see "Authenticate Email" and click that Select ...

Your application can send mail directly from its application server, provided you take some steps to ensure that your outbound mail doesn't get flagged as spam. This includes setting reverse PTR (DNS) records for the sending server's IP address. Possibly some manipulation of headers and maybe an SPF record... Another option is to relay your application's ...

Let's follow the trail of evidence here: $ whois toafinish.com | grep "Name Server" Name Server: DNS1.HOST1PLUS.COM Name Server: DNS2.HOST1PLUS.COM Those are the authoritative nameservers for your domain. Let's look at the current SPF records: $ dig txt toafinish.com +short "v=spf1 a mx include:e2ma.net ~all" "spf2.0/pra a mx include:e2ma.net ~all" ...

The source IP address of mail is almost always recorded in email headers, no matter what method you use. These serve a purpose - to track down spam, viruses spreading, etc. Sysadmins need to know where the mail came from to help stop these things. Your IP address isn't a secret. Every website and other system your computer connects to knows it. If, for ...

I would like to know some suggestions for open source solutions, I dont want something really complex ("a complete enterprise groupware solution", just the name "enterprise" gives me itches), I want a simple web based e-mail account. If a web interface is not possible, at least a *nix solution very light which supports pop3/imap. I use: Postfix for ...

Sorry, but your 90% reliability of GApps is way off. If their reliability was that bad, there's no way they would have the market share they currently do. If you insist that their uptime is that bad, I'd start looking into your own infrastructure to see if something is wrong. I've been using GApps Standard (the free version) for several personal and ...

What I did to disable local delivery. I'll be using the example.com domain. Requirements: example.com A entry pointing to IP address assigned to one of the eth interfaces. /etc/hosts defining example.com assigned to the very same IP address as above example.com MX records pointing to Google servers (ASPMX.L.GOOGLE.COM, etc) default sendmail installation ...

I am using gmail as my email provider. Ok, so I'm working under the assumption that you have an address, let's call it myaddress@gmail.com that you're sending from, and you're receiving email at google using that address. I want to send email from my dedicated server and I don't like the 500 message per day cap. Ok, you want to switch to a server ...

I host some of my personal email there (not like "I have a gmail account" but actual domain email hosted there). On the one hand, they're pretty reliable, and they're not likely to get taken down by any shmuck with a grudge against your company. You get a lot for free, and if you want more, it's pretty cheap. They do do decent spam filtering, and probably ...

You're mixing the terms a bit. Google App Engine is for developing your own services. You want to sign up for Google Applications: http://www.google.com/apps/intl/en/business/index.html When doing that, you'll get good instructions on how to relay your email through google. Both in- and outgoing.

It looks like gmail won't show the IP if the message was sent from the web interface, but messages sent from an email program, using gmail's SMTP server will have the sending IP in the mail headers.
