Description Axel Braun 2014-09-10 09:32:22 UTC

I send a mail to some 80 recipients.
The mail is stuck in the local outbox without further notice.
'Send outbox' returns same result - nothing happens, no notice.
Akonadi Server restarted - no change.
When I copy the mail to the 'Drafts' folder I'm able to send it from the Web-Frontend of the EMail service.
I then get some bounces (mailbox unavailable etc), I assume this is checked during the SMTP-Send, but the result is not displayed. When I remember this right, that worked in earlier version...

Reproducible: Sometimes

Steps to Reproduce:
1. see above

So...tested on KMail 4.14.6: Sending to 82 recipients works, to 83 fails w/o notice!
Laurent, can you maybe create your testcase if you just send to
123@outlook.com
234@outlook.com
etc, in case there are less recipients available?

Comment 2 Axel Braun 2015-06-18 13:36:47 UTC

KMail 4.14.9 - same issue :-(

Comment 3 Axel Braun 2016-02-03 11:08:24 UTC

KMail 4.14.10 as well :-(

By the way, I cross-checked with a different mailer - it is not an issue of the provider (blocking large number of recipients), it is really a KMail Problem...

Tested against KMail 5.5.3 (openSUSE Tumbleweed) - bug seems to be removed.
Close as working
