Hi,
I'm currently having a problem connecting to my IMAP server
using Emacs although accessing my SMTP server (which has
only 1 IP address) is working fine.
While trying to connect to my IMAP server using GNUtls, I
get the following error:
Debugger entered--Lisp error: (error "aol/993 Name or service not known")
make-network-process(:name "*nnimap*" :buffer #<buffer *nnimap aol nil *nntpd**-338562> :host "aol" :service "993" :nowait nil)

At the exact same time I am trying to connect to my IMAP server
using Emacs (GNUtls) and it fails, I am able to conect to the
IMAP server from the command shell prompt:
$ nslookup imap.aim.com
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
imap.aim.com canonical name = nginx.aol.com.
nginx.aol.com canonical name = nginx.mx.aol.com.aol.akadns.net.

$ telnet imap.aim.com 993

I think that problem might be related to the multiple address
results returned by the resolver (DNS) and the interaction
with the `open-protocol-stream' inner functions.
Perhaps it's failing on one of the multiple resolved IP
addresses found amd not trying the next resolved IP address
that was returned (until the pool is exhausted) before
giving up with the error "aol/993 Name or service not known"?
Thanks.
