Hi,
Enter all the mail details and click on sent button,Observe 
it display a message "message is sent successfully" ,But 
it's not displaying sent message details inn the sent mail 
option.

for that you write ths severioty and priority like this 
 Severioty -critical
 Priority  -s1

Before anyone enters a bug for this desription certain
things need to be observed first.

1. Did they get the confirmation message " sent
successfully", if so check the database and see whether it
is sent successfully.

2. Check the front end application and check whether we can
see the message in sent mail if not visible check the
message in database and view whether we can see the message
saved in sent table or not.

3. if the message do exist in database of sent mail table
then it might be the problem of getting the data from
database and displaying it to the front-end.

4. Might the problem that it is not saving in the sent mail
table properly.


These are some of the issues that might happen and we have
more too, so do check for these constraints and then report
them correctly accordingly so that they come to know we have
tested in a rightful manner.


Might help you ... if there are any other issues let me know
, might be useful to me aslo.
