[imp] Unable to send mail through webmail

[Vijeeth]

Hi All,

I have installed psa-5.0.2 on redhat linux 7.2 everything works fine .
But when I try to send an e-mail via webmail interface its just
reloading the page but the mail is not delivered to the recepient. I am
able to receive the mails from outside mail servers. I am very new to
this webmail in plesk. Aslo I tried with mail client using the same smtp
server it is working good. can any one throw the light on the problem
would be great.

I am able to see the following messages in the log files.

This is from maillog

"Mar  4 12:33:33 newserver imapd: LOGOUT, user=gvijeeth, ip=[127.0.0.1],
headers=0, body=0
Mar  4 12:33:37 newserver imapd: Connection, ip=[127.0.0.1]
Mar  4 12:33:37 newserver imapd: LOGIN, user=gvijeeth, ip=[127.0.0.1]

Mar  4 12:33:59 newserver imapd: LOGOUT, user=gvijeeth, ip=[127.0.0.1],
headers=0, body=0"

This is from messages
"Mar  4 12:33:33 newserver authpsa: IMAP connect from @ [127.0.0.1]
 Mar  4 12:33:59 newserver last message repeated 4 times"

Any modifications in the configuration files of webmail has to done ???
