Description

One user complained that he didn't received one mail sent by boutique-wifi@orange.com

The postfix log contains:
bq. /var/log/mail.log:May 26 20:10:13 orfeo postfix/cleanup28928: 3rFxyF5MZxz2J9G: reject: mime-error invalid message/* or multipart/* encoding domain: quoted-printable from relais-nor34.orange.com[80.12.70.34]; from=<> to=<>

The default value of Postfix parameter strict_mime_encoding_domain is no. The current value is yes. The Postfix documentation states:

This feature should not be enabled on a general purpose mail server, because it will reject mail after a single violation.

The command zgrep "reject: mime-error" /var/log/mail.log* allows to identify 11 rejected mails, possibly: 7 spams and 4 valid mails.

Duck, what do you think about using the default value for the @strict_mime_encoding_domain ?
