After that when I am placing hold for my patron I am receiving error mention
in 2error.log file,

Then at time of capturing hold  ,I am receiving error mention in 3error.log
file.

hold.available and hold.capture but after doing set up also ,mail is not
receiving to my id, for I aslo have setup my mail server
configuration..please provide me solution for this
