Danke, opahewi! Hat auf Anhieb funktioniert, haette ich nicht gedacht. :wine:

Ich habe das Problem oft, dass ich auf eine Antwort warte und erst nach Tagen bemerke, dass noch im Postausgang liegt. Warum ist das nur bei Opera Mail so?
Die Ursache mag an FreenetMail (in meinem Falle auch GMX mail) liegen, das Problem liegt aber bei Opera Mail. Opera Mail muesste zumindest beim Schliessen darauf aufmerksam machen, dass da noch etwas im Postausgang liegt.

Hi! I'm back again.

As sgunhouse said there must be something about that account.

I didn't realize it because I was using the mail program "Becky!" for this account and there was never a problem with the TLS setting.
(There might also be another problem with this (old) mail program.)

I contacted the mail provider but they couldn't solve it. (They even suggested to switch off the router and switch it on again after a while....)

We'll look for another email provider.

!! No problem with Opera Mail !!

:bye: :bye:

That's what I also was thinking about. So I tried again and found out the following:

It depends whether there is an attachment or not.

Port 587, without TLS: mails with or without attachment are sent.
Port 587, with TLS: mails with or without attachment are NOT sent.

Port 465, without TLS: mails without attachment are sent.
Port 465, without TLS: mails with attachment are NOT sent.

So, only 587 without secure connection is ok.

I asked the people from the server company and they asked me to try without security software. So I switched off Kaspersky, but there was no change.

They also gave me other server numbers but no change...

I checked again with other mail programs. With Outlook and Thunderbird it is the same.

Thank you all for your comments.

I have set the port to 587 but did NOT check TLS.

Now, the mails are sent out and the Outbox is emptied.

Incoming POP Server is set to 995 with TLS checked.

Thank you

Opera mail is the best of all mail programs I have used so far. I have about 12 mail addresses and also for Opera Mail is very convenient. But with one mail account I have a problem: Mails are not sent, remain in the Outbox for ever, or are sent many many times while they remain in the Outbox. There should be no problem with the setting as I tried all of them and also the password is correct. I was using Thunderbird, Becky!, and also Ms Outlook etc. and never had this problem. I guess it's a bug in the software. Or what would you say?
