hi
for several domains I have several email accounts which are all working fine when I connect with thunderbird from home.
However since yesterday I can not connect to a specific domain.
On this domain I was experimenting with Horde, Roundcube and in the end I uninstalled horde and roundcube and installed squirrelmail.
Everything is working as expected and I can receive and sent emails form squirrelmail and usermin. But not anymore from home.
When I take the emailclient on a usb stick and send an email from a different location then it works fine. Doing the same from home, it's: cannot connect to mail.domain.eu. I can telnet however to that domain.
So I think I banned myself from this domain. My colleague has no issues at all. I have no issues connecting to any other domain on the server, except this domain and only from home.
I see nothing strange messages in the logfiles available to me.
How can I find out what happened, if I banned my home IP and how to get rid of it?
Thank you
Ronald
