Sentry email notifications not arriving?

Hint: the timeout is the key!

I've been using Sentry for quite some time now in some projects, mostly all of them running python based applications and systems, and recently I did a major upgrade of a Sentry server to the latest version (8.3.1). It was an update with lots of changes, both in the Sentry internals and the dependencies needed by it (like the addition of Redis) but everything went more or less smoothly.

Once I had the server ready, I did upgrade the Raven client accordingly and I modified something in our staging server so an exception (IOError actually) was raised and the proper notification was sent to the Sentry server.

It worked just fine, the error message was sent to the server and it appeared on the Sentry web interface. Just perfect... or not?

Not really. After the error arrived in the Sentry server, a notification should have been sent to a mailing list where developers/support would see it and act accordingly. But that email never arrived and there was no error on the Sentry server logs.

When I took a look at the SMTP server logs, I found this

12:53:12 sm-mta[1534]: NOQUEUE: connect from my.sentry.server [xxx.xxx.xxx.xxx]
12:53:12 sm-mta[1534]: AUTH: available mech=SCRAM-SHA-1 DIGEST-MD5 OTP CRAM-MD5 ANONYMOUS, allowed mech=LOGIN PLAIN

12:53:12 sm-mta[1534]: u4JArC4c001534: milter=opendkim, action=connect, continue
12:53:13 sm-mta[1534]: u4JArC4c001534: milter=opendmarc, action=connect, continue
12:53:17 sm-mta[1534]: u4JArC4c001534: my.sentry.server [xxx.xxx.xxx.xxx] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

Which basically means there was an incoming connection which was suddently closed by the client.

Weird.

Cyberpunk cycling

all geared up and connected!

A view of the road from Portomarin to Lugo from my bicycle

A couple of days ago I went on a ride in the morning. One of the usual routes I do around Lugo, first going southeast towards the mountains, then turning west, then northeast back to Lugo. Around 58 kms on both main/bigger roads and small and lovely secondary roads.

Something I do quite often this days, but this time something was different.

This time I had fun x 10. I felt so good, it was so much fun, I couldn't stop smiling. I even laughed out loud some times. It was like having an extra boost of adrenaline. It was real good fun there and, at one moment, I thought that I'd love Dolo to be there with me, having exactly that same sensation, feeling the joy and the fun.

"That won't happen any time soon" - I thought. I know, I know, not everybody likes the same things, same sports... but I thought it would be really nice to be able to share that with her.

And then an idea came to mind, like a lighting strike: SimStim!.

For those of you who hadn't read (yet) Neuromancer (seriously, go read it!), a SimStim allows one of the characters on the novel (Case) to be able to connect to another character (Molly) and live her experiences as his own, seeing what she sees, feeling what she feels (pain, joy, surprise, etc).

That'd be just perfect for sharing all the joy I had the other day while riding my bike. And, who knows, the future is just there, around the corner...
