Emails from yahoo accounts with attachments not being received?

I have a client using a @yahoo.co.uk account trying to email his work domain, this is a SBS2003 exhcange server. If the email has an attatchment it, it will not be received. Although if blank or just text it goes through ok. We are using a ZyWall 5 UTM firewall/antispam and Trend Micro Anti-spam. His email address is whitelisted on both.

Thanks in advance.

Emails from yahoo accounts with attachments not being received?virus

Yahoo is still having some problems at the moment. Suggested cures range from Update Adobe Flash Player and Javascript to clear IE7 cache, cookies, and browsing history. Different things seem to work for different people. It's causing attachments to not show, 999 errors where it won't let you do a particular action and some people cannot send recieve delete or move mail. It's not just Vista either it's happening to some of us on XP. I have been advised to use this site to view my mail, www.mail2web.com if all else fails go back to classic mail via this link. http://us.mg1.mail.yahoo.com/dc/optout?s... click yes when asked do you want to opt out. Hope this helps.
