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

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

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

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

When sending an mail to domain at example.com I know it's translated to
joe at example.com but the @example.com get stripped off, and servers
host.domain.tld added. From imap logfile:

Weird. I'm still clueless.
