Hi, I have a program that send mails to selected customers. I upgraded it to Delphi 2007 and Indy 10, because the in previus version (Delphi 7, Indy 9) there was the problem that all mails sended was considered spam. The new version worked fine from summer until now, where only with some mail servers, again mails are considered spam.

Wath can I do to fix this problem?

Thanks very much. Angdrak
