Post subject:  Does gmail banned my sales email address?
Hi,
I have many email address on my linode.

If I send email from my davide@myserver.org to gmail no problem,
if I send email from my sales@myserver.org to gmail gmail does not receive this email,
no error but the gmail user will never receive my mail.

Any idea on why of this?

Thanks.

I don't think that google banned my sales email. I noticed that google reject also the "support" email...
Do you know if gmail has some problem with aliases?

Is the return address valid (i.e., will your server accept mail sent to sales@myserver.org)? Many receiving mail servers check to see if the address sending mail is valid before accepting mail from it.

Best thing to do is probably to tail your mail log while sending a message from sales@ and see what the discussion with the gmail server looks like in real time.

Code:
tail -f /var/log/mail.log
(or whatever your mail log file is).

Here's what a successful transaction looks like from Postfix:

Code:
Sep 10 08:10:36 brightstar postfix/pickup[28133]: 35A46141C5: uid=1000 from=<username>
Sep 10 08:10:36 brightstar postfix/cleanup[28675]: 35A46141C5: warning: header Subject: Test from local; from=<username@myserver>
Sep 10 08:10:36 brightstar postfix/cleanup[28675]: 35A46141C5: message-id=<20130910151036.35A46141C5@myserver>
Sep 10 08:10:36 brightstar postfix/qmgr[27663]: 35A46141C5: from=<username@myserver>, size=376, nrcpt=1 (queue active)
Sep 10 08:10:37 brightstar postfix/smtp[28715]: 35A46141C5: to=<username@gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.129.27]:25, delay=0.93, delays=0.01/0.01/0.22/0.7, dsn=2.0.0, status=sent (250 2.0.0 OK 1378825837 sl4si17533021pac.184 - gsmtp)
Sep 10 08:10:37 brightstar postfix/qmgr[27663]: 35A46141C5: removed


The second to last line, where it says "250 2.0.0 OK..." will reflect an error message of some kind if gmail is refusing your mail.

sure, I have sales and support in the aliases and my server is accepting mails on that addresses, it simply redirect mails to my personal email address when some email is sent to that address.

Is the missing mail in the Gmail user's spam folder?

Do you have spf/dkim records set? (I've found google pays close attention to spf records)

In my experience, click "Not Spam" when it happens and Google will eventually figure it out.

I don't know what spf/dkim is.
What is it? How can I check?

Check here http://support.google.com/a/bin/answer. ... swer=33786 it's aimed at google apps so you'll have to adjust it for your own set up. SPF is easier than DKIM, you can ignore DKIM if you wish most providers are happy with just SPF

wow, this is good to know, thanks!
I'm using the linode dns manager, how can I add "this SPF" in the linode manager?

Add a txt record which looks something like this
v=spf1 mx a ~all
That will allow emails from your MX records and A record. If you send from other servers you can add them with a:fqdn

what does it means ???
Code:
v=spf1 mx a ~all


can I add a TXT with that string without warry about making spammers life easyer.
what does it means that string?

don't I need to use something like this:
v=spf1 a:mydomain.org ~all
and another line like this:
v=spf1 mx:mydomain.org ~all

doesn't this two line more secure than "v=spf1 mx a ~all" ???

v=spf1 states that it's a SPF record. A means that any server that has an A record for your domain can send email, MX means your receiving email servers can also send. You only ever want one spf record. Also make sure you have rDNS configured properly.
