If I sent an e-mail to myself in the TO box it is very fast sent and arrives instantly in the IMBOX folder to read.

If I sent an e-mail to myself in the CC box it is not sent, or it is very slow sent. It shows in the SENT folder but until now, almost 2 hours late, not shows in the IMBOX folder.

If I sent an e-mail to another server (like @gmail.com) is the same, goes to SENT folder, but the other person (@gmail.com) doesn't receive the e-mail that I sent.

Please verify and returns faster than possible.
