Hello community,

Luckily, there are only a few topics dealing with mail problems... I've read them all, but could not find a solution:

My backdrop cms refuses to send e-mails... user registration, password reset, webforms: "Unable to send e-mail".

The log messages do not reveal much: "Error sending email (from ... to ...)"
The server logs do not have entries about mail attempts.
Te spam folder in my mail client are empty.

This is what I tried so far on two different installs (1.27.1 and 1.28):

1. Using php mail function, at admin/config/system/site-information I tried two different mails (info@real-domain.com & info@other-domain) – same result:

When reseting password: "Unable to sent e-Mail"
When creating an new account: "Unable to sent e-Mail" AND "A welcome message with further instructions has been emailed to the new user". But no mail is coming in.

2. Using smtp authentication support
More or less the same behaviour:

• Blue message: 
SMTP ACTIVE: Mail delivery is handled via SMTP module.
SMTP ACTIVE: Mail delivery is handled via SMTP module. (yes, twice)

• Green message
The configuration options have been saved.
A test e-mail has been sent to test@test.com. You may want to check the logs for any error messages.

• Red message
Unable to send email.

The recent log screen shows "Error sending email (from ... to ...)"

Does anybody of you has an idea what else I could try and test?

Thanks in advance and best regards

Hello again,

I did some more testing:

  1. On the same server I have running a drupal 10.2.6 instance – sending mails with php is no problem.  (both site use php 8.2.19 fast-cgi)
  2. I did a completly fresh backdrop 1.2.8 install, with no additional module at all – same prolem: "Unable to send e-mail"
  3. On my hopefully-near-future-live-site I installed the maillog module and can see there that the mails are "produced". Allthoug the mails aren't sent, Maillog doesn't mention this.
  4. I noticed the during installation of backdrop the site-mail was generated automatically : noreply@domain.com. Is this the normal behaviour?

And, may be this is another topic or maybe it has a relation to the mail problem: When trying to delete/cancel a test-user, a get a white site  after saving. 

Looking forward to any  advice...

 Thanks and best regards
