It seems to hang when I try to read my mail

This is often a problem if you are using POP3 instead of IMAP, and you have more than a few hundred messages in your mailbox.

By default, php is set up to time-out a request that takes over 30 seconds to complete. phpGroupWare must do a lot of work the first time your POP3 mailbox is opened, and every time you get new mail, which may take more than the 30 second timeout.

You can either clean up your mailbox with another mail program, or add the line

set_time_limit(0);

to the top of the inc/phpgwapi/phpgw_msg_pop3.inc.php file, just before the line class msg extends msg_common

If you choose to edit the file, be patient when loading a large POP3 mailbox - the author tested against a mailbox with 2500 messages in it, but it took 15 minutes to load the page. We highly suggest you use IMAP if you expect to have more than a few hundred messages in your mailbox.
