[Dovecot] Sieve vacation not working

[Marcelo]

It only works without :addresses for me

And even when getting this on confirmation the logs:

Feb 24 09:03:52 localhost dovecot: lmtp(7895, a1 at dum.li):
yeIlOfjN61TXHgAA0J78UA: sieve:
msgid=<451bb443b8ad815c205a2cce07ac31aec0727c47 at vm-atmail7>: sent
vacation response to <a2 at dum.li>

It wasn't working.

This did the trick on CentOS 7 though:

alternatives --set mta /usr/sbin/sendmail.exim

Cheers
