From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Description of problem: The sendmail.cf config defaults to a 5 second timeout on identd lookups. What this means is that anyone connecting to a Redhat mail server and not running identd (most Windows clients) will experience a 5 second delay while the Redhat box times out on the identd time. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Telnet to port 25 on Redhat server running sendmail from a client without an identd server (Windows) Actual Results: Five second hang will be experienced before getting sendmail prompt. Additional info: I would recommend changing the default identd timeout in sendmail.cf to 0s or something lower than 5 seconds. This can be changed directly in the sendmail.mc used to build the cf file... #O Timeout.ident=5s should be something like O Timeout.ident=0s
Why are no rejects done from Windows? Looks like a bad firewall configuration that could be the cause for this? I agree that identd is not very useful, but will probably leave the default settings for now. Florian La Roche
