Slow when sending email from webmail client

Hi. I'm having an issue where any email sent from my webmail clients either squirrelmail/roundcube/horde are taking up to 30 seconds to send out. Upon clicking the 'send' button I have to wait +- 30secs before the page proceeds. This problem has occurred just recently, before this it was working ok. There haven't been any changes to the network within that time. When sending e-mail through the outlook or other desktop clients, it gets sent immediately.

Anyone faced this problem before? Any ideas on how to resolve?

Appreciate any help. Thanks.
