Hi, a few days ago all my boxes using the same ISP stopped to send me emails from local users and daemons (daily outputs and any other cronjob reports) to @gmail.com. I have tried to send email to a few not_gmail mailboxes - the same problem. If i send emails from other boxes (using other ISP), they are received correctly.
Telnet test doesn't show the "220 mx.google....." line. Does is mean that port 25 is blocked by the ISP? $ telnet gmail-smtp-in.l.google.com 25 Trying 173.194.220.26...
