We have had a recurring problem since about October, where our emails through our SQL 2016 database will intermittently fail throwing this error:
Message The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3. Exception Message: Cannot send mails to mail server. (Failure sending mail.).
Again, some emails are successfully delivered on the first try, others are delivered on the 2nd try, and some fail to be delivered on both attempts.
We are using smtp.office365.com port 587 with basic authentication, SSL checked.
TLS 1.2 is enabled and showing correctly in email headers, but I am unable to see the cause as to why some emails are failing to go out, while others are successful.
I see no packet loss to the office smtp IP during one of these failures either. The server itself is updated to the most recent .NET framework as well.
Apologies if this information is inadequate, I am not too familiar with this whole concept and trying to learn as I go.

We have a SQL Server 2016 Standard Edition. I set up the SQL mail service (account + profile) on it a year ago, which worked perfectly (account: smtp.office365.com:587, SSL, basic auth).
Since October 11, 2021, there have been constant problems with sending mail. In many cases, sending mail doesn't work, I get the following error message:
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2021-10-27T18: 07: 10). Exception Message: Cannot send mails to mail server. (Failure sending mail.).)
Here is an excerpt from the sysmail_allitems table:
I don't understand what the problem is because the server sends the email once but not the other time.
Do you have any idea what might be causing the problem?
I am using SQL Server Management Studio V18. I would like to schedule a job in SQL agent, which will send some mail based on some condition. For that I have configured database account profile and I am trying to test the email. But email is not received. It is saying the below error. any help on this will appreciate.
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 1002 (2021-03-30T05:36:55).
Exception Message: Cannot send mails to mail server (The operation has timed out
My suggestion is to either connect "in the clear" or use a custom or 3rd party program. This (maddening) issue has been with SQL Server for over a decade and, for us, it was because of using a secure connection (time outs - some mail never sent - yada yada). Our email server gets the connection credentials, so it IS communicating with it - (handshaking), but there's a bug with SSL when it comes time to deliver the message.
Our solution was to create a CLR C# program that gets called and delivers messages correctly. You can look for a 3rd party emailer as well. SQL email will always disappoint.
I have configured different ways and tried to send test email , didn't work.
Error: The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 5 (2018-01-22T14:28:24). Exception Message: Could not connect to mail server.
(A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 74.125.24.108:587). )
Configured the database Mail as blow.
I have tried possible changes but still getting failed.
1.Verified all usernames and passwords
2.Checked with different ports 465 ,587 and default 25
3.pinged SMTP.gmail.com its working
4.Control antivirus and firewall settings
I have refereed
Sending Email through SQL Server FAILED
any other ways ?
Please check your settings on GMail. You need to switch on the 'Allow Less Secure Apps' setting so that it will allow third party apps such as SQL Server to access the GMail servers.
How to access the Outlook server to sent email using SSIS.There is an email account ,which can be used to sms to any mobile number using outlook server.when try to use the smtp server to send sms it gives an error
[Send Mail Task] Error: An error occurred with the following error message: "Mailbox unavailable. The server response was: 5.7.1 Unable to relay".
so,planning to use outlook server instead of smtp.
It seems, Smtp is not allowing the email account(from) to send email/sms to a domain other than internal addresses!?. Though this works perfectly fine with the outlook server
You need to use the email address for the phone number; For example my number on AT&T in USA is read more like 123456789#text.att.net. You should have something similar and you wont have to worry about SMTP or any other setting.
I have a SMTP server by using which I was smoothly sending e-mails using sp db_mail.But now I am not able to send any DB mail using the same profile, all the configuration from SQL Server is fine, but instead getting the following message in Error log
Message
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 2 (2016-04-21T04:09:58). Exception Message: Cannot send mails to mail server. (Failure sending mail.).
)
P.S. By using the same SMTP server, I am able to send Mails from another IP.
The telnet thing is getting aborted when I tried it from the command line.
Any ideas?
