We switched email hosting to Rackspace and haven't had an issue since. &nbsp;Shame on the old provider for having issues, being blacklisted in places.

This issue has become frustrating for me since I can't seem to find a solution...<br />

One of my users is having issues sending email attachments to his customers. &nbsp;It generally affects PDF files but sometimes JPGs and it's only a small number of customers that if affects, certainly not all. &nbsp;We're using Outlook 2013 and this is a simple POP3 account. &nbsp;He receives no bounce back message, just a response from the user on the other end saying they didn't get the attachments. &nbsp;It's bizarre. &nbsp;I've uninstalled, reinstalled, removed accounts, setup accounts, checked A/V, disabled A/V, checked our firewall, checked with our ISP and I can't find the smoking gun. &nbsp;Has anyone ran across something similar here? &nbsp;I'm at a loss. &nbsp;<br />

Thanks
