And also

[root@host1 mail]# cat /etc/mail/mailertable

however when im sending email to the virtual user im getting this error,

Apr 19 20:52:13 host1 sendmail[22311]: q3JHqDAR022309: to=<jamal@example.com>, ctladdr=<root@host1.bigmama.com> (0/0), delay=00:00:00, xdelay=00:00:00, mailer=dovecot, pri=120292, relay=dovecot, dsn=4.0.0, stat=Deferred: dovecot mailer (/usr/libexec/dovecot/deliver) exited with EX_TEMPFAIL

Dovecot LDA can’t deliver the mail to the user!!!
