Sendmail on FreeBSD error

feylya

In work, I'm using a FreeBSD server to generate mails in a .local domain which go to a second server in the .local domain to be forwarded to my .com domain. I can send mails from the first server to any address except my .local domain. It just will not find the second server. DNS seems to be set up fine. MX record is being found but when I try to send a mail and run mailq, I get this:

-----Q-ID----- --Size-- -----Q-Time----- ------------Sender/Recipient-----------
lASIs913024886        5 Wed Nov 28 18:54 <admin@test1.example.local>
                 (Deferred: Name server: test2.example.local.: host name lookup f)
                                         <test@test2.example.local>

It seems to be a fairly common error but I can't find a fix for it. Anyone have any ideas?

OK, I can email from the first server to any domain but the .local one. Exchange on the .com domain can email the .local domain. I'm completely stumped

Make a copy of your sendmail.cf file

Head into sendmail.mc

Check this line

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Try putting a dnl at the start of that line.

Quit sendmail.mc

open the access db in the same folder

Check that you have access setup for your local domain.

Kick off the make command you find at the top of the sendmail.mc file, restart sendmail.

Hope that helps. Make sure you back up your sendmail.cf and sendmail.mc files!

feylya

Thanks. The DAEMON_OPTIONS doesn't appear in the .mc file and access.db is set up. Still no luck though.

GreenHell

Really?

I've only used sendmail on rhel so there is probably a version miss match.

This is the bounced email I get back:

This server can send to any other domain, just not example.local :mad::(

GreenHell

No expert on sendmail now, but maybe its a problem with how your domain is setup.

Can you dig example.local , would it be possible that .local is a character too long?

feylya

This is the output of dig example.local

I'm replacing the real domain name with example btw. The real name is shorter.

GreenHell

How about mailing to test1@<theipaddress> ?

feylya

Exact same.

Snowbat

What about these?
dig @ad.example.com example.local
dig @hostmaster.example.com example.local

Don't know what the craic is with hostmaster. Looks like it's something to do with DNS on Active Directory

Snowbat

That is the cause of the error your Sendmail reported - it can't get the MX or A record for example.local so it can't determine which server receives mail for that domain:

550 5.1.2 <test12345@example.local>... Host unknown (Name server: example.local.: no data known)

SMART_HOST might be more suitable for your setup?

No luck there unfortunately

Something I've just realised - I can't telnet to 25 on test1 from test2. Dunno how much difference that'll make - I'm only using test1 to send emails, not receive
