Dear Community,
recently I noticed that some emails do not get delivered to the recipient. I did not find any error in the logs, email cue is empty.The admin support on the other end notice a “[smptp] closed by quit”. I am quite shure that this is not a nethserver problem.
- I have this problem only with one service supplier - if it would be nethserver, I should have more problems
On the other hand, the error on the other side “[smptp] closed by quit” points to nethserver:
- All I find on google about this error is related to rsampd / exim ?
- It seems to be a time-out?
Log files on the recipent side:
