Title: using port 24 for e-mail
Post by: Anonymous on March 14, 2004, 02:36:52 AM

I have been trying to get my sme 6.0 machine to use port 24 for e-mail without any luck for days.  I am setup at dyndns.org and have successfully used this service with an SME 5.12 box.
 
I made all the necessary changes to the following templates:

/etc/e-smith/templates/etc/rc.d/init.d/masq/30AdjustTOS
   # Set telnet, www, smtp, pop3 and FTP for minimum delay
    for port in 21 22 23 24 80 110
    do
        /sbin/iptables --table mangle --append OUTPUT \
            --protocol tcp --dport $port \
            -j TOS --set-tos Minimize-Delay
    done
    # Set ftp-data for maximum throughput
    /sbin/iptables --table mangle --append OUTPUT \
            --protocol tcp --dport 20 \
            -j TOS --set-tos Maximize-Throughput

/etc/e-smith/templates/etc/rc.d/init.d/masq/45AllowSMTP
{
    my $status = ${'smtpfront-qmail'}{'status'} || "disabled";
    my $access = ${'smtpfront-qmail'}{'access'} || "public";
    $OUT = allow_tcp_in(24,
            ($status eq "enabled") && ($access eq "public"));}

/etc/e-smith/templates/etc/services/10standard # /etc/services:
smtp            24/tcp          mail

I even followed the instructions at
http://www.elhoj.dk/new/index.htm?frame=http%3A//www.elhoj.dk/howto.htm

I can receive mail, but cannot send.
Via IMP I get the following error.
There was an error sending your message: unable to connect to smtp server localhost:25

reasons for failure log reveals the following.
del  xdelay  reason
  5  311.83  Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)/I'm not going to try again; this message has been in the queue too long.
telnetting to port 25 reveals the following
telnet *.*.*.* 24
Trying *.*.*.*.42...
Connected to ip*-*-*-*.tc.ph.cox.net.
Escape character is '^]'.
220 router.davesshop.net mailfront ESMTP
So, that looks good.

Any and all help is appreciaited!
Thanks,

What are you trying  to fix using port 24?

Are your ISP blocking your port 25? Mine do that!

I solved this by forward all domain email to one mailbox on one ISP, and configure SME to download each five minutes.

BTW: Port 24 is LMTP (local mail transport protocol!) a well know port/protocol!!

Jader,
Yes, I am trying to get around my ISP which I successfully did with my SME 5.1.2 box.  I ended up bringing it back up and putting my 6.0 box off to the side as a backup.

Why change the way everything works... (I know... you did it with 5.12...)?

Just let SME use fetchmail to download all email from  your_mailbox@your_isp and delivery. Or at least while you don´t fix new version of SME!

Now the questions:
How you do to everyone try to connect you on port 24 (not blocked by your ISP) instead of port 25... I thought this was not possible! :)

Could you please do a HowTo about how to change SMTP from :25 -> :24 ) ? :)

Thanks
