I noticed I wasn’t really up to date, and so I launched system update.
Immediatly after system update, messages have been sent.
Could be a coincidence, but I don’t think so.
E-mail was in the queue since around 9:00 AM, and I tried many times to attemp to send receiving the same message in the maillog.
Immediatly after upgrade (around 11:30 AM) I used /etc/e-smith/events/actions/system-adjust comand (not sure it is necessary), et volià, messages have been sent
Anyhow now it seems everything it’s properly working
never use Alice’s smtp servers… if you can’t move away from TIM/alice connectivity, find a smtp service (free or not) outside… alice is unreliable, their servers are too often in some BL and appear to be undersized…
if you care, take a look at sendgrid.net… you can send 12000 mail/month for free… (and yes, you can disable email tracking stuff)
Alice’s smtp servers as relay host shoud be temporarily.
I’m waiting to understantd if Aruba can insert a PTR record with the IP of the server, so I can stop using a relay host.
ok, take a look around, there are other services (Mandrill is another one, IIRC) or take a look at https://aws.amazon.com/ses/ (IIUC, 0.10$ for 1000 sent emails)
