Thank you for your answer, unfortunately you're quite right :( It didn't even cross my mind until I read your mail and checked the homepage of my ISP, and there it stood, the announcement of blocking the port 25. That sucks, but I guess there's not much I can do except change my ISP... Anyhow, thank you, very helpful, Juha -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
