Email clients not working properly

[Vladis]

Hi I am running pfsense 2.0.3 It is great for my needs but the only problem that I have is that PFSENSE is blocking or disconnecting emails with attachments, I have tried with thunderbird and outlook. I believe it is important to mention that I can send emails without attachments perfectly.  If I disable the firewall it work as expected but I really need the FW rules to work properly.

Can someone please let me know how can I fix this issue??
I will appreciate your help enormously.

Regards Vladis
