Hi Meaulnes,

> ... Deferred: Connection timed out with mail.domain.tld.

Is mail.domain.tld your server? That's the one that's not accepting your
emails. This could be because they have issues, a misconfiguration or
maybe some rule they have set up interferes with the delivery.

hello list

I don't get it: recently, e-mails sent from one virtual server to anotherone on 
the same 5209R box are rejected with the following:

... Deferred: Connection timed out with mail.domain.tld.
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old

• I couldn't find out from which senders domains it happens, fromgmail.com 
senders for instance it doesn't happen
• sendmail and dovecot are running without errors
• the senders aren't listed in the APF blacklist.
• after 5 days nothing is sent

I rebooted the servers but it didn't help, the e-mails sent from and to domains 
on the same 5209R box are deferred and not sent. If I send them from my gmail 
account, they are accepted.

any ideas what's going on?

thank you and best regards

I believe you need the legler.co BEFORE
the co entry as the search stops on the first
hit.

just for the sake, here is my /etc/mail/access snippet:

# exclude TLDs Begin
# inserted on Michael's advice by ml 10.5.2019, 8.2019, 10.2019, 1.2020

the .co domains are rejected, but legler.co isn't (if I did it right)

Hi David,


Is this something that gets over written on a update and works with
postfix?

It'll work in Postfix as well.

Put the lines Larry suggested in /etc/mail/access and then restart
Postfix (if you're using Postfix):

systemctl restart postfix

Restarting Postfix will cause it to parse the sendmail configs and it'll
incorporate these changes into the Postfix config as well.


Thank you Michael and Larry.

These are the steps I used on the 5210R

MAIL ACCESS
# block access to top level domains
cd /etc/mail
vi access

# add this below the local host section
# TLD's We Don't Allow Begin
asia    REJECT
best    REJECT
casa    REJECT
cyou    REJECT
live    REJECT
work    REJECT
# TLD's We Don't Allow End

# hash
makemap hash access.db < access

# restart postfix
systemctl restart postfix
