I am running and comparing my $$$$ Surface Pro 11 (OLED) with my abused Surface Pro 1796 (I7 running Win 10). I use my eM Client on both (as well as Outlook). On the expensive new machine I am periodically getting successive emails ‘stacking up’ and perhaps not being sent. I get notifications that the emails are undeliverable and being rejected by the recipients server. Some are evidently received because I get a response from the recipient. Then I get a message that the rejected messages are okay to resend. My old Win 10/Surface Pro 1796 does not have such eM Client issues.
I like things about my new $3000 device. I hope issues with eM Client are soon resolved.
If you get an email to say the message is rejected by the recipient’s server, it has been successfully sent from your computer and delivery has been attempted by your email provider’s server. The email application is no longer involved.
As it has not been delivered to the recipient’s mailbox, that is probably an issue on the recipient’s server. Usually it will say why, like mailbox doesn’t exist, or mailbox is full etc.
It may also say something like your IP address has been blocked. If your IP address is blocked, that is something you will need to discuss with your Internet provider.
I suspect that the recipient’s mailbox was full. In this case, the recipient must have received the message because I had already received her reply about an hour earlier. We exchange multiple emails daily, and it is just the occasional one that I get the “rejected by recipient’s server’” message. I also get a follow-up message that the original is now “okay to resend”.
Anomalies that I do not understsnd. Thanks Gary!
