[imp] IMP loads attachment but won't send message

[Derek Colley]

Hello,

I have the following setup on my gateway:
- Mandrake 9.0
- Apache 1.3.26
- PHP 4.2.3
- Horde 2.1 & IMP 3.1
- PostgreSQL
My IMAP server is out there on the internet somewhere...

I am able to attach a file to an email, but when I click Send nothing gets
sent and the Compose window times out. Trying anything on the main [Horde]
window also times out. I have to shut down the browser and start again.

Can anyone tell me where to start looking?

Rgds,
Derek
