Looking for help sending email to a gmail address from my cron. At the top of crontab

MAILTO="obfuscated@gmail.com"

But no mail comes. Checking /var/log/maillog, I see

Dec 17 22:46:36 myserver postfix/pickup[30426]: CC21261C6E: uid=501 from=<root>

Dec 17 22:46:36 myserver postfix/cleanup[30486]: CC21261C6E: message-id=<20181217224636.CC21261C6E@myserver.novalocal>

So, clearly, the IPv6 version is blocked, but the fallback gets a success message, yet no mail ever arrives. Same messages if I try using the command-line mail command. However, I can use the command-line mail program to successfully send mail to my company email address.

mail -s "test1" obfuscated@mycompany.com

test1

EOT

The telnet trick seems to indicate I can access the gmail server:

$ telnet gmail-smtp-in.l.google.com 25

Trying 108.177.98.26...

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

Escape character is '^]'.

^]



telnet> quit

Connection closed.

My IP tables look like this

Chain INPUT (policy ACCEPT)

target     prot opt source               destination         

ACCEPT     all  --  anywhere             anywhere            state RELATED,ESTABLISHED 

ACCEPT     icmp --  anywhere             anywhere            

ACCEPT     all  --  anywhere             anywhere            

ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:ssh 

ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:http 

REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 



Chain FORWARD (policy ACCEPT)

target     prot opt source               destination         

REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 



Chain OUTPUT (policy ACCEPT)

target     prot opt source               destination         

Any help on this will be greatly appreciated.

Thank you @ivanivan. Gmail was organizing all my cron output into the Spam folder, which is not displayed in the Gmail interface by default. (This seems like the right thing to be doing since the sender "root@myserver.novalocal" is pretty sketchy.) Once I displayed the Spam folder and looked inside, I saw all the cron output. (Look at me telnet'ing into mail servers and reviewing iptables.) Doh! ... Thank you again ever so much.
