Title: TCP trigger DIALD
Post by: Patrick Schepers on February 09, 2002, 02:41:19 AM

I'm using SME 4.1.2 with an external ISDN modem

What is triggering DIALD when a client is sending e-mail to an external adres?

I'm trying to stop this because I want to send mail externally by CRON

I have already tried modyfing DIALD.FILTER by adding

ignore tcp tcp.dest=tcp.smtp
ignore tcp tcp.source=tcp.smtp

I even changed everything which starts with UPD to ignore it
ending with "ignore upd any"
and still the connection to my ISP is triggered and e-mail is delivered

in the logfiles is read

trigger tcp 192.168.0.150/1170 194.109.6.49/25

can anyone help to figure out what is triggering DIALD when via a client a email is send.

Thanks

Usually it's a DNS lookup, which is UDP port 53.

That's an SMTP delivery attempt. The DNS lookup which precedes it probably succeeded out of the local DNS cache.

Hello Charlie,


I diabled all UPD statements ending with

ignore UPD ALL

and still the e-email was delivered.

Do you know to way to stop delivering e-mail externally?
