I know. What I meant was that it looked like it wasn't processed correctly.
Meanwhile I've found out that for me that happened because I forgot to
add the test domain to local-host-names. Correcting that fixed my
problem. With almost the same config your setup is now working for me.

I have example.com in local-host-names and FEATURE(`use_cw_file') in

the .mc file. That's not it.

So it's interesting to see where your config differs from mine:

I have
Mcyrusv2,       P=[IPC], F=lsDFMnqXzA@/:|m,
                S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP
                T=DNS/RFC822/SMTP,
                A=FILE /var/lib/imap/socket/lmtp

I got my lmtp socket in /var/imap/socket which I believe is the standard.

The Cyrus V2 Mailer specification from cyrusv2.m4 look like this:

Mcyrusv2,    P=[IPC], F=lsDFMnqXzA@/:|m,
        S=EnvFromSMTP/HdrFromL, R=EnvToL/HdrToL, E=\r\n,
        T=DNS/RFC822/SMTP,
        A=FILE /var/imap/socket/lmtp

And the same from my cyrusv2.mc file:

Mcyrusv2,    P=[IPC], F=lsDFMnqXzA@/:|m,
        S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP,
        T=DNS/RFC822/SMTP,
        A=FILE /var/imap/socket/lmtp

I took the E= out for now, as it doesn't seem to do anything.

So the same except for the E= item (I think that's to add > to quoted
messages?).

The > quote thingy is done by the MUA. In my case SqirrelMail.
 

I'm not sure about what the E=\r\n but it was something about default line endings,

witch later was changed to LF (\n) as default.

The last time I was fighting with issues like this it was because of the
mailer definition. What happens if you remove the E= portion?
I do understand correctly that the bottom mailer definition is the one
you're using, right?

Both definitions end up in sendmail.cf, with the one from .m4 first, followed

by the one from .mc immediately after.

I'm also assuming the
# Virtual user table (maps incoming users)
Kvirtuser hash -o /etc/mail/virtusertable
class is present in your sendmail.cf?

Yes, it's in there.
 

I use
testdomain.nl             cyrusv2:/var/imap/socket/lmtp
in mailertable

Anything that you have different?

Well. I'm not using mailertable. I want to use the virtuser function, to forward

specific addresses to users on other servers.

When sending an mail to domain@xxxxxxxxxxx I know it's translated to

joe@xxxxxxxxxxx but the @example.com get stripped off, and servers

host.domain.tld added. From imap logfile:

Weird. I'm still clueless.
