Can you stop your firewall for testing purposes to see if it works then?

 

Hello,

No good. No log found.

Code:

tcp 0 0 *:pop3 *:* LISTEN 527/pop3-login
tcp 0 0 localhost:dyna-access *:* LISTEN 2415/clamd
tcp 0 0 *:imap *:* LISTEN 8841/dovecot 

I wonder why it reads pop3-login for pop3 and Dovecot for imap... Maybe Dovecot isn't listening on POP3, maybe it's a different daemon? Can you access your mails if you use IMAP?

 

Hello,

I decided to use IMAP instead POP3 but, I never removed the POP3 option. I am able to access emails via Dovecot with Claws Mail in Linux , Outlook in windows and RoundCube online: with RoundCube I am able to send email.

Kind regards,

Al

 

Can you kill the pop3-login processes and restart Dovecot? What does

Code:

netstat -tap

show then?

 

Hi,

Done, here is the output

Regards,

 

Now there's no POP3 daemon at all. Do you have pop3 and pop3s in the protocols line of your /etc/dovecot.conf?

 

I remove POP3 protocol from dovecot.conf. I do not use it at all. I am using IMAP. I am not able to sand email from a client?

Any other suggestion?

Regards,

 

Oh, I was thinking you were using POP3... Are there any errors in your mail log when you try to fetch mails with IMAP?

 

Hell
I tried outlook and I am getting the followin error...
