Incoming mail not receiving

[PaulOMahoney]

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)
Processor: Intel
Email Client: imap

Problem: I can send emails but cannot receive emails though 1 or 2 emails have filtered through over the past few days.
I have checked my web based email "Squirrel Mail" and there weren't any of the missing emails on this.
When I send mail I get the following message

Error
Unable to add message to IMAP mailbox. The corresponding local folder will be used instead.
Error: - 17495

This appears some of the time but not always. PLEASE HELP!
