[AMaViS-user] How to bypass header checks

[Chaminda Indrajith]

Dear All,

Mmails received from our customer are always rejected by Amavisd-new.
This is due to some swidish characters in the Subject Line.

Amavis Alert shows the following.
X-Amavis-Alert: BAD HEADER Non-encoded 8-bit data (char C3 hex):
Subject: [Tic4355] Trollh\303\244ttan - Priceli...

Is there a way of bypassing header checks of amavisd for all mails
receiving only from that cutomer.

Regards

One option is to not perform this particular test (invalid non-encoded
8-bit characters) on headers (for all senders):

Also look at some of the examples in amavisd.conf-sample, search for
%final_destiny_by_ccat

Another option would be to create a policy bank designed to bypass
header checks for a particular client(s) or sender(s). If you are
using Postfix take a look at exampes 5,6,7 here:
