I tested with the GRP file provided and have not been able to reproduce the issue.  When the message is rejected during the SMTP session, what is the error being written to the logs?

We are using version 26.0.0 I dont think I'll see anything on the log because as soon as user with post permission click send, we get an error saying you cant send to this address or something sim...

Is MDaemon Connector being used to send the message or is the recipient using it to view the message?  Or Both?  Can you upload a copy of the MSG from the user's sent items folder from th...

I will add your requests to our wish list to be considered for future versions.

I'm not sure why gmail would be throttling messages because an address was provided in the CC field, but I'm glad you were able to resolve your issue.

Well, I went in to copy and paste one of the delayed posts in the Remote Q and I happened to see, From:  To:  and CC:  populated. CC: had the same gmail address as To:  That cau...
