so now how can i send mail without having this problem ?
This is because Google will reject any emails sent from IP in the spamhaus database.
What you need to do is go to http://www.spamhaus.org/lookup/ and follow the instruction there to remove your server ip from spamhaus database.
Please also follow this guide: Prevent mail to Gmail users from being blocked or sent to spam
You can find the answer at the link in the last line of the Google mail served response:
'The IP you're using to send email is not authorized...'
In order to prevent spam, Gmail refuses mail from IP addresses that are not authorized to send mail. The determination of whether or not an IP address is authorized to send mail is made by the ISP that provides you with the IP address. This list typically contains consumer IP ranges offered for dialup, DSL, or other broadband access.
What can I do to fix this?
Your ISP may provide SMTP relays which will accept mail from your IP, and these servers should be authorized to send mail. Some ISPs may provide a way to get an IP that is authorized, either by upgrading to business class service or static IP service. You should reach out to your ISP to see what options are available.
Another alternative is to send mail through your own domain’s servers, either by configuring them to allow relay from your IP address, or by using MSA (mail submission agent). Learn how to use Gmail to send mail from a different address.
Please note that we are unable to whitelist IP addresses or otherwise make exceptions.
In other words, if your IP address is not authorized by your ISP to send mail, you should send your mail through:
Your provider mail server (SMTP relay)
Your own domain mail server.
Mail servers must meet a number of requirements to prevent their messages from being blocked, e.g. have a PTR record. The use of authentication methods such as SPF, DKIM or DMARC minimize the chance that messages are marked as spam.
I had this problem with one of my hotmail addresses, using Thunderbird on Kubuntu. Tried changing sever settings, passwords etc to no avail. In desperation, I deleted the offending email address through "account settings" "account actions" (bottom left of window). If you are on POP3 you will loose all your emails, so make sure you're on IMAP.
You then just select "add email" in Thunderbird and the email is put back as it should be and works perfectly.

I have an exchange server 2016 and I've created a user, say testuser1#exchangedomain.com
I followed the steps as told in this video:
https://www.youtube.com/watch?v=GN2mZ6qOWf8
I'm trying to send a mail from testuser1#exchangedomain.com in the exchange server to any outlook account in the outside world, for example, username#outlookdomain.com
But I'm unable to send a mail from testuser1 and I'm receiving this error on the exchange server
Remote Server returned '550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient not found by SMTP address lookup'
Is it even possible to do so because both the domains are completely different or am I missing something here?
The recipient email account is not found or doesnot exist. Even sending an email from Gmail gives "Address not found
Your message wasn't delivered to username#outlookdomain.com because the domain outlookdomain.com couldn't be found. Check for typos or unnecessary spaces and try again".
I am trying to send an email using the smtp.office365.com server. It always return the same error:
5.7.57 Client not authenticated to send mail.
As far as I know, the problem is related with the fact that I'm working with ADFS. So I have previously federated my domain to work with Office 365. When I try to log in to Office, I'm redirected to the login page of my platform, which is fine.
Is there a way to send email using the Office smtp server when working with ADFS?
Not to my knowledge, you need to change the primary username to use your tenant domain rather than your federated domain. Then you'll be able to log in without ADFS.
We configured a single account for SMTP with just an Exchange Plan 1 license, and then set up internal SMTP relays using that account to transmit to O365. We then limit connections on that account to only known locations. Then we add SendAs permissions for that account to all the DLs/mailboxes that we need to send email from.
I am trying to setup Sendinblue and use it as an SMTP server for my marketing and general Odoo 12 email messaging.
I setup every thing in Sendinblue and tested the SMTP Server in Odoo and got a "sucess" message under Settings / Technical / Outgoing Mail Servers.
For this I setup an external smpt server with the following data:
SMTP Server: smtp-relay.sendinblue.com
Email: my sendinblue email
Password: Password provided by sendinblue
Port: 587
Security: TLS (STARTTLS)
I can test the connection with success and set this SMTP Server as the server for sending email campaigns from Email Marketing / Settings / General Settings
Created a test email campaign and tried to send it and test it with no luck.
When Odoo tries to send the message, returns a "not delivered email" message with a unique reference and my local PC name, something like:
989345297097442.1625436965.401543280300903-openerp-reply_to#MYPC-NAME
I confirm sender email is registered and validated in Sendinblue. Using the same email as sender in Odoo.
Tried to do the same with my personal gmail account but even activating less secure apps, no message is sent from my instance.
What could be wrong?
I found the problem.
I had to verify the domain name I use for sending emails from Sendinblue service.
I have done it Senders & API main menu option on "domain" tab.
After verifying my domain name, everything is running fine
I am trying to send mail with my yandex mail account on database mail. Actually it was working for a long time. Last 1 month I cannot send mail with my yandex account. Always it gives that error message,
Error,16492,The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 10 (2014-11-08T17:20:25). Exception Message: Cannot send mails to mail server. (time out ).
The mail account works with Microsoft Outlook, but it does not work with database mail. I am also using SSL secure connection. Which is in the configuration of database mail account?
Thank you.
It's a late response but it is a true solution.
With Yandex kindly use SSL port number 587 instead of 465.
Screenshot Yandex IMAP settings
Also add IMAP settings, SMTP does not work without it
I am trying to setup windows server 2008 smtp server to relay emails to gmail smtp. Everything appears to be setup but it is not sending emails. Could you please help me figure out whats wrong.
Below is the setup:
Windows server 2008 with SMTP server
feature installed. Need SMTP server
to forward all messages to gmail smtp
server to send.
I have google apps setup for my
domain, also I can send emails
throught my test app using
gmail smtp.
SMTP Server Configuration: By default has default smtp server virtual directory.
In Properties of that virtual smtp server changed following.
Fully qualified domain name = mydomain.com
smart host = smtp.gmail.com
TCP Port = 587
Out Bound Security = Basic Authentication(my username password for google apps email account)
In domains list under virtual smtp server. I have one default domain that's server dns. I added another one for my domain name.
With above setup i am trying to redirect all email to gmail smtp.
I tested connection to smtp.gmail.com from server on port 587 through telnet and it works.
I am trying to use above server from my web application also by just dropping emails in pickup directory. It get's picked up and also accepts request form web application but never sends an email.
I can see that it adds those emails in queue folder but it stays there forever.
When i try to send emails from web app to above server it rejects if To address is other than my domain.(Am i missing something in list of domains)
Thanks for all answers, finally found solution there is a property for maximum sessions which value was 0 by default. Changed it to 100 and it send all pending emails immediately.
Possible reasons are that some SMTP servers block the outgoing messages if there domain name mismatch, possible to prevent spam mails from being sent. So for example, I will not be able to send my email with an address abc#mydomain.com from my domain yourdomain.com.
Hope that helps.
Ensure your sending domain is the same as the google apps domain
Ensure your sending address is a real address and not just an alias
IIRC you need to use STARTTLS (SSL) not basic authentication
This souds like a DNS issue. Check your /badmail directory. It will have .bad and .bdp files in there. You can open these in notepad (there will be some binary in there).
However, it may point to the possible problem.
You may also want to try and enable logging on the SMTP service. There may be something in there.
