The CN on the certificate (which happens to be ipostoffice.worldnet.att.net) needs to match the name of the host you're accessing (which happens to be ipostoffice.att.net) or you'll get this warning. If AT&T told you to use "ipostoffice.att.net", then they're certificate is configured with with the wrong name. However, notice that both host names point to the same host (ping both names, and you'll see they evaluate to the same IP address) - so you can just change the host name you're using to the one expected by the certificate (ipostoffice.worldnet.att.net) and the warning will go away. If AT&T told you to use the other name, however, then I would expect this to work only until they correct the certificate with the proper value. _______________________________________________ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
