Hello, thank you for your reply. I'd like to provide 2 quick additional details before trying your suggestions: 1) If I add a from address at the command line, then mail is delivered ok: $ mail Alеxander.Farber at gmail.com -r wеbmaster at prеferans.de But if I just run $ mail Аlеxander.Farber at gmail.com then it is rejected by Gmail. So I could append "| mail -r wеbmaster at preferans.de" to all my cronjobs, but I'm looking for better solution 2) My ISP (hetzner.de) doesn't provide mail relaying at all. Regards Alex
