Problem Sending Email With Attachments

by Ric Galit on December 10, 2008

If you are one of those email account users that is having a problem sending emails with attachment try modifying your outgoing SMTP port from 25 to 587. Most ISP blocks traffic on port 25 unless you are using their services (or their server) to send email. Please note that port 25 will still work as long as your ISP is allowing it. Port 587 is an alternate port that was included in the new setup when all the hosting accounts managed by Mavicus I.T. Solutions were moved to Houston, Texas.

Below are some screenshots on how to modify an existing Microsoft Outlook 2007 configuration.

Step 1: Click on “Tools > Account Settings…” from the toolbar menu.
