 FairEmail does not hide errors like similar apps often do, so it is easier to diagnose problems.
 Also, FairEmail will always retry again later, so transient errors will automatically be solved.

 The message *... Read timed out ...* means that the email server is not responding anymore or that the internet connection is bad.
 
+The message *... ParseException ...* means that there is a problem with a received message, likely caused by a bug in the sending software.
+FairEmail will workaround this is most cases, so this message can mostly be considered as a warning instead of an error.
+
+The message *...SendFailedException...* means that there was a problem with sending a message.
+The message will almost always include a reason. Common reasons are that the message is too big or that one or more recipient addresses are invalid.

 See [here](https://linux.die.net/man/3/connect) for what error codes like EHOSTUNREACH and ETIMEDOUT mean.
