Hi,

in src/lib-smtp/smtp-address.c line 759 the localpart is compared with null_strcmp, which does not ignore the case. While this is the correct behavior (according to the RFC) it causes problems in real life.

In my case the vacation notices are not sent, if someone writes to First.Last@ruhr-uni-bochum.de because :addresses contains (only) first.last@ruhr-uni-bochum.de.

In practice if you convert the username part to lower case in the MTA then you will accept mail with mixed case but only have to deal with lowercase in Dovecot.
