Exim times out on incoming SMTP connection

L.S.

I can't get exim to receive mail through SMTP because of a time out.
When I send messages locally everything goes fine. But receiving from
outside domains doens't work.

telnet 192.168.2.112 25 gives me an immediate 220 response.

telnet mail.eaze.org 25 gives me a 220 response after about 30secs

then I opened port 113 on my router and then

telnet mail.eaze.org 25 gives me an immediate 220 response. Is this
normal???

But when I go to http://www.dnsreport.com and ask for a report on
eaze.org I get a time out in the mail section.

Does anyone know what's going on?

Thanks in advance...

Sincerely,
Patrick Holthuizen

Are you starting exim using exim -bd ?

Yes,

I discovered that my ISP blocks port 25 for all their clients and offer
a relay server to redirect, so my problem is solved. The only question
left is the necessity of port 113. Can you explain it to me?

Sorry for only posting this link, but there is all information needed:
http://grc.com/port_113.htm


Also external testings if your port is open/closed/stealth
are nice for testing purposes.
They provide information about most ports.

In your exim.conf, "rfc1413_query_timeout" controls how long it will
wait for a response on port 113 "Identification Protocol". The
following line will tell it to only wait 5 seconds.

rfc1413_query_timeout = 5s

If you're using WHM/cpanel, in WHM go to "Exim configuration editor"
and select the "edit raw config" button. Put this line in the box at
the top and go down to the bottom of the page and click save. Exim
will now only wait a max of 5 seconds for a response on ident port
113.
