SMTP 465 not working, forced to use 25

Hi all,

I have LAMP with postfix running smoothly. I did notice that upon configuring my Thunderbird on my Debian dektop, and K9 on my Android device, that I can configure port 993 for incoming, but it refuses to connect to port 465 for outgoing. I am being forced to use 25. Where can I look to get port 465 configured properly for my IMAPS setups?

My router has ports 465 & 25 currently opened and pointed to my email server.

Thanks

I think if your router have these ports open then you can use them for successful email server.

 

Thanks Srijan

I can email in/out out of the squirrelmail, no problem there.

My problem is that I cannot configure port465 on my Thunderbird or my android K9 app.

I can configure port 993 for incoming on my thunderbird and K9.

But I cannot configure outgoing 465, only port 25.

Thanks

Well Update;

Looks like my ISP is blocking those ports (465 & 587). I opened them in my router, but scanning those ports still show them as closed.

Port 25 is open, but since I am using a DNS redirector, my dynamic IP is being blacklisted on a couple of spamhouse services.

So I guess my next question is: Can I setup nonstandard ports for smtp so that my devices can still SSL/TLS with my server? Do I need an SMTP relayer for my server to email out without being blacklisted?

Thanks

Yes generally ISP's uses to open the port 25 for all customers as this port in general used worldwide for the email communication.

Yes you can.

Yes, the best thing you can do.

 

This is what I am getting:

Code:

root@mail:/home/adminpc# netstat -tap | grep smtp
tcp        0      0 *:smtp                  *:*                     LISTEN      27547/master

I was thinking that the nonstandard ports would be the communication between my mailserver and the syncronized devices, but all the incoming/outgoing mail would go through the mailserver first before sync'ing with the devices.

Maybe I am thinking about this all wrong......

Is it just the /etc/mail/main.cf file that I add the smtp relayer to? Or is there other files that I have to edit?

Thanks

Hi Till,

this is my master.cf file now:

Code:

smtp      inet  n       -       -       -       -       smtpd
#smtp      inet  n       -       -       -       1       postscreen
#smtpd     pass  -       -       -       -       -       smtpd
#dnsblog   unix  -       -       -       -       0       dnsblog
#tlsproxy  unix  -       -       -       -       0       tlsproxy
submission inet n       -       -       -       -       smtpd
#  -o syslog_name=postfix/submission
#  -o smtpd_tls_security_level=encrypt
#  -o smtpd_sasl_auth_enable=yes
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
#  -o smtpd_recipient_restrictions=
#  -o smtpd_relay_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
smtps     inet  n       -       -       -       -       smtpd

And this is what I am getting now:

Code:

root@mail:/home/adminpc# netstat -tap | grep smtp
tcp        0      0 *:smtp                  *:*                     LISTEN      6546/master     
root@mail:/home/adminpc#

Is it enabled now?

Looks like the relayer needs a user/pass.

What would the other files be that I need to edit?

Thank you

Heeter
