[imp] IMP- Default Identity Problem

[Jayanta Ghosh]

Dear All,

I have installed the following components on our server:-

    * Horde: 3.3.6
    * Imp: H3 (4.3.6) 
    * Mimp: H3 (1.1.3)

Everything is ok except the compose part of the mail. There the default 
identity is without the domain name, i.e userid@ and for this reason i 
am getting an error message @.SYNTAX-ERROR. 
</horde2/imp/message.php?mailbox=INBOX.Sent&index=165> When i am setting 
the default identity from the option list it has been saved for that 
session only.I want to set this default identity permanently.

Please help...

Thanks & Regards,
Jayanta
