[Users] WG: [Bug 3252] smtp authentication at smtp server of GMX fails - permanent error - no sending

[Juergen Gaida]

"Until you've found AND fixed a problem, 
    what you discount will likely be the source."

So, FIXED.

It was indeed a settings failure - an unobvious one for me, obvious for others?

I had an invalid entry in "configuration > account settings > advanced > domain name".
I thought the domain name there is the domain name of the email provider.
But, exactly this caused the server to refuse authentication as it collided with his internal
names...or so. Still a bit confused why it did work so long...

Now that I have chosen a different name, it runs.
Maybe I will untick the box later on...to avoid any trouble at that point (again).

So thanks for looking into and sorry for the trouble...

Best regards
Jürgen

I left them blank as well as I filled in the user name and password  -  no change

My standard was/is to leave it blank.

No, Authentication via POP3 before send is not required - and does not work if I switch it on.

And, yes, it is the right server and the right port.

It all worked for weeks and then it stopped, all by a sudden. Then it worked again (without changes
on my system) and after some weeks it stopped again - this time persistent.

So, you are right, unless I have not sorted out all possible sources of the failure, I cannot be
sure to be at the base line. 

And my own failure is also possible and it truely was often enough - just a missed tick or a tick too much,
a typo, a wrong number... - more often than the software....

So, lets see where I will end up this time :-)

- are you sure you are pointing SMTP at the right server/port? I ask
  because my provider has different servers for different account levels
  -- my main mail goes to a secure server, while some of my other lesser
  accounts go to a normal, less secure server. In addition, the
 secure
  server even uses a very non-conventional 4-digit port.



BTW, this is the .signature file I used circa 1990 after several years
involved in the Internet's early deployment days:

   "Until you've found AND fixed a problem,

That was my way of saying the most difficult problems usually have a very
simple/subtle cause which is/was too "unlikely" to take seriously... :) :)

Good luck,

Pierre
