sendmail NOT WORKING anymore...

[smallufo]

I didn't change any line of my code .
I deployed my app about one year ago and never touched it ever since.
Today , I found I didn't receive any emails from my app.

The log reports OK ,but I just cannot receive any emails sent from
GAE.
gmail , hotmail ... just cannot receive these emails...

It's not over quota...
The emails are not in the SPAM folder , either...

What's wrong ? Any solutions ?

1 year is a long term. I assume you've already ran your app (unit) tests with the latest SDK version?

I have the same problem, the last mail sent that was received was two days ago, but since then no mails have been received, but there are no errors logged or anything. Didnt change anything, it just stopped working.

Can you telnet to port 25?  For example, if your application IP name is smallufo.com, you should be able to give the command

telnet smallufo.com 25

and the mail server should reply with something.

For example:

jeffsilverman@jeffsdesktop:~$ telnet smtp.gmail.com 25

Trying 2001:4860:8005::6d... <=============================== this is an IPv6 address, you will probably get an IPv4 address

Connected to gmail-smtp-msa.l.google.com.

Escape character is '^]'.

220 mx.google.com ESMTP ud10sm27733287pbc.25

If you see that, then sendmail is running and listening to the internet.
