What does the sender has to do?

Hello,

an (for us) important newsletter was blocked by our Spam-Filter. The reason for this is the following:

2006:09:29-09:21:34 (none) exim[17192]: [43\50] X-Spam-Score: 4.6 (++++)
2006:09:29-09:21:34 (none) exim[17192]: [44\50] X-Spam-Report: 
                                                                       1.5 SUBJECT_ENCODED_TWICE Subject: MIME encoded twice
2006:09:29-09:21:34 (none) exim[17192]: [45\50] 0.9 UNDISC_RECIPS Valid-looking To "undisclosed-recipients"
2006:09:29-09:21:34 (none) exim[17192]: [46\50] 1.2 BIZ_TLD URI: Contains an URL in the BIZ top-level domain
2006:09:29-09:21:34 (none) exim[17192]: [47\50] 0.0 MIME_HTML_ONLY BODY: Message only has text/html MIME parts
2006:09:29-09:21:34 (none) exim[17192]: [48\50] 1.1 FROM_EXCESS_BASE64 From: base64 encoded unnecessarily
2006:09:29-09:21:34 (none) exim[17192]: [49\50] 0.0 SUBJECT_EXCESS_BASE64 Subject: base64 encoded encoded unnecessarily
2006:09:29-09:21:34 (none) exim[17192]: [50/50] X-Spam-Flag: YES (tagged as spam, score 4.6) 

Can anybody explain, what the sender has to do so the mail will not be blocked in the future?

Btw - sure, now the sender's mail-adress is in the whitelist, but I think the best way is to change the newsletter...


Thx,


Jan

  • Hello,

    our threshold is 3 - agressiv. We could not increase this...

    I would prefer if there is a possibility to reduce the spam-score of this newsletter.
  • If you could explain me what the problem is, I think we could try to change that in the newsletter.
  • Well, according to what you've posted:

    Apparently, the email contains a URL that has a .biz domain in it.. that's adding 1.2 to the score--if the resource you're linking to has a .com or .net domain name registered, use that instead.  Also, it appears that the mass emailing program being used to send the newsletter is double-encoding the email.. I'd contact the maker of the email program in question to find out why it is doing this.

  • Thanks for your reply,

    can you explain me, what a double-encoded email is? 
    When I search in the internet I found many links to the MIME-format of mails, but no explanation.
  • ask your email system vendor about it.. they should be familiar with this issue.
