This might seem obvious, but did you make sure your mail server has a PTR record for it's IP? If not, make sure your mail server has a PTR record in DNS and do a dpkg-reconfigure -plow sendmail.

Actually, no, you don't (and there is no such error msg in sendmail).

You seem to be a victim of the same broken "helpfulness" as described in the (apparently misthreaded by google) thread at
http://groups.google.com/group/comp.mail.sendmail/browse_frm/thread/7095fe4c3569eed1
i.e. some install script or whatever has "configured" your sendmail with a *host name* of literally " ;; connection timed out; no servers could be reached"! This is actually an error message from the 'dig' command - i.e. the script probably tries to use 'dig' to get the fully-qualified host name, and blindly accepts any output from 'dig'. The slightly different greeting comes from the fact that sendmail inserts the "ESMTP" there as the second word, under the reasonable assumption that the host name is a single word…
> 250 2.0.0 l0P4LLHX023711 Message accepted for delivery > test@email.addr... Sent (l0P4LLHX023711 Message accepted for delivery)
So the submission went OK, despite the repeated "error messages".

This occurs when the MTA relays your message to your smart host - the sender should have received a bounce with a more detailed explanation than "Service unavailable", but it's a good guess that the broken host name makes the remote complain and reject the message, or the whole transaction - e.g. it would result in a syntactically invalid HELO/EHLO command for starters.

Newsgroups: comp.mail.sendmail From: vladina...@gmail.com Subject: WARNING: local host name (;; connection timed out; no servers could be reached) is not qualified; see cf/README: WHO AM I? Date: 11 Jan 2007 10:21:00 -0800
I am using Sendmail 8.13.5 on Ubuntu 6.10. I keep getting the following error, and nothing I do seems to be able to fix it. Google has been less than helpful, as has ubuntu's official and non-official support forums, and sendmail.org's documentation has been sadly unhelpful. Sendmail, it seems, cannot find the local host name. This is despite it being correctly set in /etc/hosts, in /etc/mail/local-host-names, in DNS, etc.
I've verified that DNS works. All other errors have been squashed. When issuing a make all, or a sendmailconfig in /etc/mail, I get the follow error:
WARNING: local host name (;; connection timed out; no servers could be reached) is not qualified; see cf/README: WHO AM I?
The sendmail.org documentation suggests the use of
FEATURE(use_cw_file)
which is already in my .mc
It's interesting to note that " ;; connection timed out; no servers could be reached) is not qualified; see cf/README: WHO AM I?" actually shows up in the sendmail.cf in a variety of locations (like $j). Manually editing the .cf (bad, I know) and restarting sendmail seems to have no beneficial effect.
Even our local sendmail guru is confused. Anyone have any other ideas?

The sendmail documentation referred to by the error message, i.e. the "WHO AM I?" section of the cf/README file, certainly doesn't suggest that, but rather setting confDOMAIN_NAME in the .mc file (which ends up setting $j).

Wow - I guess the "helpful" Ubuntu people try to generate .mc and/or .cf with some tool, but forgot to check for errors…
> Manually editing the .cf (bad, I know)
Well, having that garbage in it is definitely worse!:-)
> and restarting sendmail seems to have no beneficial effect.
Have you checked that the .cf isn't auto-regenerated from a .mc that has the garbage in it when you "restart" - putting such "helpful" stuff in rc scripts seems to be common in Linux distributions. Try to find the .mc file and check/modify it - like cf/README says, normally there is no need to set confDOMAIN_NAME at all. And of course also check that the _.mc_ file doesn't get auto-regenerated with garbage in it! Finally, remeber that there are two .cf (and .mc) files in 8.12 and later, sendmail.cf and submit.cf - you didn't say in what context you got the error message, if it's on direct invocation of sendmail in non-daemon mode, it's coming from submit.cf.

Ok, so the "Temporary system failure" is due to "World writable directory". But /etc/mail/ is not world writable?!
The /etc/ is. Fix it and try again:
