Hi, I have an application written in Delphi2007 and Indy 10, that send mails with attachments to persons. All works good, but a strange thing happen, if I connect the mail box using a webmail all is ok, and the attachments are visible, but if I connect to the mailbox using a client program as thunderbird or outlook, all attachments disappears. I suspect that the problem could be in antivirus scanning, but the files attached are pdf files. Now there is some magics that must be setted in the sntp component before sending that avoid this? And if so how must be setted?

Thank you very much, Angelo
