SMTP outgoing random ports

[philly75]

Hi All,

Can anyone please advise why my server gets random ports for outgoing mail?
Running this: netstat -plan| grep :25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 23511/exim
tcp 0 0 0.0.0.0:2525 0.0.0.0:* LISTEN 23511/exim
tcp 0 1 192.168.1.110:48673 65.55.92.136:25 SYN_SENT 21525/exim
tcp 0 1 192.168.1.110:48671 65.55.92.136:25 SYN_SENT 24051/exim
tcp 0 1 192.168.1.110:48672 65.55.92.136:25 SYN_SENT 23016/exim
tcp 0 1 192.168.1.110:36137 65.54.188.94:25 SYN_SENT 24308/exim
tcp 0 0 :::25 :::* LISTEN 23511/exim
tcp 0 0 :::2525 :::* LISTEN 23511/exim


192.168.1.110 is my servers internal IP and I have submitted a form off my web page, and this is what i see displayed as connections on port 25, see the server IP attached to random ports?

I have installed vestacp, all the default ports for smtp are active, 25,465,587,2525

I have opened my firewall for these SMTP ports to ALLOW to the server but does not.

POP works but SMTP does not.I have removed sendmail and postfix, so only exim and devcot is running.

Anyone have any ideas?

Thanks
Phil

Hi,

Send an email somewhere or attempt to send one and then run that same command.

Thanks

/etc/exim4/exim4.conf.template

Code: Select all

daemon_smtp_ports = 25 : 465 : 587 : 2525

/etc/exim4/exim4.conf.template

Code: Select all

daemon_smtp_ports = 25 : 465 : 587 : 2525

Yes I have this in exim.conf (not exim4)

daemon_smtp_ports = 25 : 465 : 587 : 2525

I dont have exim.conf.template file:
/etc/exim/exim.conf.template
-bash: /etc/exim/exim.conf.template: No such file or directory

Same here.

It seems that VestaCP is doing this or perhaps NGINX reverse proxying something.

There is no way that anyone else in this forum has not come across this and fixed it. If not then no on is using a firewall policy based and has all ports open to public.

I am behind a firewall and I have a BLOCK all rule to my server and have opened ports 80, 443, and all SMTP ports:
25 : 465 : 587 : 2525 and I have opened POP3 before smtp on firewall.

Exim though chooses random ports to send out. Who can help and how to fix this?
