Follow-up Comment #26, sr #106478 (project administration): I think I am beginning to realize why you can post directly but notifications are not delivered.
When you post to a GNU mailing list (or to me personally, it doesn't matter), the message is picked by fw-pool-128.gruppocredit.it (your ISP/company's SMTP server, I guess) and it passes through several hops at yourhostingaccount.com, rewriting the envelope to something like <[EMAIL PROTECTED]>. I believe this is what the gnu.org server performs the callout verification for, e.g. the following (simulated) check happens: telnet mail.yourhostingaccount.com 25 [...] mail from: <> 250 2.1.0 <> sender ok rcpt to: <[EMAIL PROTECTED]> 250 2.1.5 <[EMAIL PROTECTED]> recipient ok So the verification succeeds, and therefore delivery. By contrast, when you do a commit, cvs.savannah.gnu.org (the CVS server) constructs the message (with the help of log_accum.pl) with envelope <[EMAIL PROTECTED]> (your Savannah account), which is then changed by savannah.gnu.org to <[EMAIL PROTECTED]> (the email address you registered at Savannah), and passed along. This is the what's being verified then, and the verification fails with this cryptic error (which is easily reproducible in a SMTP session, as I've shown in comment #23). It looks like this error is something specific to this email service provider. Such a check by automatically constructed messages like the CVS commit notifications are always going to fail to deliver to hosts which perform (again, entirely legitimate) sender callout verification. Options: 1) If you have control over the server configuration of yourhostingaccount.com, please do the necessary changes so that this particular check succeeds. It is a non-standard behavior if it does not, like now. (It looks like this is some large hosting company, so I doubt this is realistic.) 2) Inform their support about this problem, and ask them to solve it (it seems others have encountered it too, and probably reported it, but it's still worth trying). 3) Stop using their service. This might be very inconvenient depending on how your things are set up. Anyway, just mentioning it as an option. In any event, let's wait for the GNU sysadmins. (Disclaimer: Obviously I'm not an expert, so I might be very wrong in all of this.) _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/support/?106478> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
