I have a strange problem: I use gentoo-linux and after merging latex my hole system behaves strange.

Although I could receive and send emails for a long while, now i am not able to send them - but receiving works fine.

I do not use any firewall or s. (like iptables) and so I trie a 'telnet $HOSTNAME 25' which ended in following error:

telnet darkstar 25
Trying 146.140.4.78...
telnet: Unable to connect to remote host: Connection refused

But also a 'telnet $HOSTNAME' gives the same error... What does this mean?

So I tried to make a 'telnet $ISP_SMPT_ADRESS 25' and receive:

telnet smtp.tiscali.de 25
Trying 62.26.116.130...
telnet: Unable to connect to remote host: Connection refused

But if I connect with ssh to another machine I get from there:

telnet smtp.tiscali.de 25
Trying 62.26.116.130...
Connected to smtp.tiscali.de.
Escape character is '^]'.
220 webmail.tiscali.de ESMTP Service (6.7.019) ready

So I think MY port 25 doesn't work!
(remember I can receive emails and surf the web, so I have some TCP connections)

Could someone help me?

Thx,

Robi

first what is your email server software? if it can recieve emails from other email servers, this means your tcp 25 port is working.
does "telnet 127.0.0.1 25" work?

No, 'telnet 127.0.0.1 25' doesn't work, too. I use Mozilla 1.5! I thought that sending mails is about port 110.

Why is there this difference :

telnet pop.tiscali.de WORKS FINE, BUT...

telnet smtp.tiscali.de DOESN'T WORK!

I think here lies the answer, but I don't know further....

Do you?

sorry, i thougth u have an eamil server. but u just have an email client software mozilla. it is really strange. u cannot telnet to port 25 of your isp's email server. but it works for other computers which is in same network. i really cannot undertand what s happining.

call your isp. maybe their firewall doesnt allow u to connect smtp.
