Hi Guys,

I have ran some tests, and this is my conclusion :

I send a mail using Roundcube webmail , this is SpamAssassins result :
X-Spam-Status: No, score=-1.4 required=4.5 tests=ALL_TRUSTED autolearn=ham
ok , so we have a MINUS result, impressive, I didn't expect it to be positive because I'm on the auto-whitelist.

Now, using the exact same mail sent in afterlogic, this is the result :
X-Spam-Status: No, score=3.9 required=4.5 tests=AWL,HTML_MESSAGE,
     MIME_HTML_ONLY,RDNS_NONE,TVD_S PACE_RATIO autolearn=no version=3.2.5

wow, 3.9 ? For a message sent by a trusted source. That means that most of my messages going out to a SpamAssassin filter ( 50% of the world ) will be marked as spam because I'm not on their whitelist and thus get a 5 score or higher.

This is a serious issue with Afterlogic and should be on the number 1 priority issue list of development team. I unfortunately have to go back to Roundcube until this major issue is fixed, because most of my outgoing mail will be marked as Spam when I use Webmail Pro.

Can you please confirm that both the mails (from Roundcube, and from AfterLogic WebMail) were sent through the same SMTP server, that both the apps were installed on the same machine, and sender/recipient details were identical?

yes, the roundcube and the afterlogic webmail are installed on the same system. Both use the same postfix server and same spamassassin ( all runs on 1 server ). The mails never left the server, they just passed through the spamassassin, I sent them to myself as test.

This is how I installed SpamAssassin btw, ( postfix is a standard install ) :

# apt-get install spamassassin spamc
# groupadd -g 5001 spamd
# useradd -u 5001 -g spamd -s /sbin/nologin -d /var/lib/spamassassin spamd
# mkdir /var/lib/spamassassin
# chown spamd:spamd /var/lib/spamassassin
# vi /etc/default/spamassassin
ENABLED=1
SAHOME=”/var/lib/spamassassin/”
OPTIONS="--create-prefs --max-children 5 --username spamd --helper-home-dir {SAHOME} -s ${SAHOME}spam.log"
PIDFILE=”${SAHOME}spamd.pid”
# sa-update
# vi /etc/spamassassin/local.cf
Modify this file looks like below
rewrite_header Subject [***** SPAM *****]
required_score 2.0
report_safe 0
use_bayes 1
use_bayes_rules 1
bayes_auto_learn 1
skip_rbl_checks 0
use_razor2 0
use_dcc 0
use_pyzor 0

# /etc/init.d/spamassassin start
# vi /etc/postfix/master.cf
Change
smtp inet n – – – – smtpd
into
smtp inet n – – – – smtpd
-o content_filter=spamassassin

and then, at the end of master.cf file add the following lines

spamassassin   unix    &n bsp;  –       n       n     ;  –      – &nb sp;     pipe
user=spamd argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}

# /etc/init.d/postfix reload

Just to make sure that this is not just me, could anyone from this forum who also uses WebMail Pro please go to spamscorechecker.com and test their mails for spam score ? If you get anything more than 5 you can be sure that 90% of your mail will not be read by anyone you're sending mail to. I got a score of 5.2 for sending a normal message. I sent the SAME message using Horde and Roundcube and both messages got a score of 0.

Aren't you sending different messages (e.g. HTML in AfterLogic case and plain-text in RoundCube/Horde case)?

Alex

Thanks Merc,

So it's not just me then. I just tested a HTML mail from Horde ( for Alex from the helpdesk ) and it came back with score 0. X-Spam-Status: No, score=0.0 required=5.0 tests=AWL,HTML_MESSAGE autolearn=ham

Love to see more test results.

MIME_QP_LONG_LINE can indeed be a problem. The QP lines may not exceed 76 characters. We'll look into this. However, this has nothing to do with MIME_HTML_ONLY rule which is just silly. It seems that to satisfy the spam filter, you have to make your e-mail twice larger (no good) and include the plain-text part which will be used only by this spam filter but not a single mail reader program in the world (the days of mailers which were capable to read only plain-text have gone ages ago). And considering the fact that most spam mails do include plain-text part, the useful effect of this rule is questionable.

Earlier, we did include the plain-text version in e-mails generated by the WebMail but since many people were asking to make emails smaller (if you check mail with a mobile device, the mail size matters), we removed the plain-text part.

Seems we'll have to make this a setting (whether to include plain-text or not).

Regards,
Alex

Any update on this being added as a feature? A lot of our clients are marking our emails as spam.

I believe the version which includes the modifications affecting that behavior is on its way and will become available for download within next 24 hours. Just in case, the version number is 5.0.6, be sure to check VERSION file under webmail directory.

This is to let you know that WebMail Pro (PHP) 5.0.6 is available for download now. Plaintext part of emails is always included, but the HTML composition was rewritten to ensure lower spam score.
