holasz asked:

A sender from France is trying to send an email to us. Unfortunately his email is being rejected with the message below. I suspect there are some weird characters in the mail content but how can I allow the content to be accepted in our mail server. Thanks

My answer:


Here is a relevant log entry:

Sep 16 11:18:49 mail postfix/cleanup[18651]: 150225EA1F3: reject: header To: <tt.otano@turintia.com>,??<ased@serapea.it>,??"Lemestre cmm" <cmm.Lemestre@frenchhost.fr>,??<jitka.grva@cedok.cz>,??<partenaire@octopode.fr>,??<michal.sky@europe-mountains.c from mailhost.vvf-vcs.fr[217.109.xx.xx]; from=<pl.pl@frenchhost.fr> to=<booking@mydomain.nl> proto=SMTP helo=<mailhost.frenchhost.fr>: 5.7.1 message content rejected

As you can see, it refers to the email To: header, and there are invalid characters in that header.

Your sender should check his mail program and ensure that it is constructing email headers properly.
