Timer job failed

Question

Dear all,
I am running timer job to bring in some data sent to trainers. but the timer job is failing in central administration - without much information. When I try to debug the code said in one area trainer FullName - the CopyFieldMask value as 'trainer.CopyField.Mask'
threw an exception of type 'System.ArgumentException'.
Can somebody throw light on this.

Hi,
If you want to get a item field value, you need to get by its internal name, you can use the CAML Query Builder to get the real internal name.
For the error message, it is related to the SMTPClient host and port configuration, you need to specify the valid hostname and port id.
Here are some similiar thread for your reference:
