Description Stanislav Brabec 2003-08-22 14:01:09 UTC 
Please fill in this template when reporting a bug, unless you know what you
are doing.
Description of Problem:


Steps to reproduce the problem:
1. Have a machine, which have both IPv4 and IPv6 address.
2. Run SMTP server, which listen only on IPv4 port.
3. Try to send mail via this machine (use its name, not IP).

Actual Results:
error message telling that it can't connect to port 25 of selected machine

Expected Results:
Try IPv6 address first, if it fails, try IPv4 address, too.

How often does this happen? 
Every time.

Additional Information:
It has ugly workaround - fill IPv4 address, not server name to Evolution.
Comment 1 Jeffrey Stedfast 2003-08-22 14:06:00 UTC 
this only happens if you build evo explicitly to use IPv6
Comment 2 Stanislav Brabec 2003-08-22 14:10:14 UTC 
Yes, I have used --enable-ipv6.

But in heterogenous environment it should be able to contact IPv4
address, too, evein in this particular case (for example KMail does it).
Comment 3 Jeffrey Stedfast 2003-08-22 14:16:21 UTC 
what's the point of having an IPv6 address if it isn't going to work?
this is a network problem, not an evolution problem.
Comment 4 Stanislav Brabec 2003-08-22 14:41:22 UTC 
Transition phase. Network can be in state, where some services are
already IPv6 ready, but others not yet. General problem, not related
only to Evolution.

Two examples from real life:

- You have a IPv6 network, but SMTP server is not yet IPv6 ready and
listens on IPv4 only.

- Both machines have IPv6 addresses, SMTP server listens on IPv6
address, but somewhere between them is firewall, which drops all IPv6
SMTP requests.

In these cases you cannot use IPv6 enabled Evolution, but you can use
other IPv6 enabled client without any problems.
