Connectivity loss produces problem with e-mail system of OKM

 #5197  by baiki
 
Dear community,

Since we have very unstable Internet connections, it seems that OKM has a few issues with trying to re-connect to mail server (it lookes like OKM tries just once). I also realized that OKM silently drops e-mails (notification and subscription) if the connection was quickly down. Is there a way that OKM tries periodically to reconnect and try to send cached outgoing e-mail notifications instead of just deleting/dropping/forgetting them?

Here's a part of my server.log:

I can confirm, the PropertyGroups error is gone. Even if the test server is not connected to the Internet, users may login without having long timeout periods. What I really don't get yet is how this setting influences the outgoing mail pooling to our SMTP server. Will try more in the meantime...

Cheers,
