I'd suspect it's either logging to /var/log/mail* or /var/log/messages
Have you checked both?

I forgot:

camille log # netstat -ptln
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address
tcp 0 0 0.0.0.0:143 0.0.0.0:*
LISTEN 4311/dovecot

And are you connecting via IMAP in your clients, the server addresses
are correct, you can telnet to your mail server on port 143, etc?

I checked both /var/log/mail.log and /var/log/messages, yes

And I am connecting via IMAP.

My public IP address is 70.234.122.254

This may be a typo but you posted your public IP address is
70.234.122.254 then tried to connect to 70.254.122.254. One is 234 and
the other is 254.

If not a typo, I thought only I could do something like that. LOL
Carry on.

Are you port forwarding port 143 through your NAT if you're using NAT?
Are you allowing imap in your firewall rules?

I'd also try the suggesting of changing to listen = * suggested here.

You were right, when I try the correct IP address, it tries and tries

From nmap:

143/tcp filtered imap
443/tcp filtered https

So yes you have a firewall and you have not checked the rules? That's
generally what filtered means.

This may be a typo but you posted your public IP address is
70.234.122.254 then tried to connect to 70.254.122.254. One is 234 and
the other is 254.

It's explained in the config comments, but turned off by default

# Log file to use for error messages, instead of sending them to syslog.
# /dev/stderr can be used to log into stderr.
log_path = /var/log/dovecot
