[opencms-dev] newsletter problem - multiple unwanted txt attachments

[aruc97 at virgilio.it]

hi,

i have successfully installed latest newsletter module 
Alkacon_OAMP_Newsletter_1.0.1 onto opencms 7.0.4
in a 
linux+apache+tomcat (mod rewrite) multisite environmet;
...
no problem 
with the newsletter creation;
no problem with user subscriptions:
actually, we have 1300 active subscribers;
opencms is correctly set up 
with an internal mail server (latest sendmail);
...
the problem is 
related to the "newsletter sending" phase:
when we do the newsletter 
send command inside workplace,
the newsletter is sent to all the 
subscribers,
BUT the resulting message sent, presents inside 
header+body unwanted txt attachments of the newsletter itself;
every 
sent message has multiple txt attachments
that grow with to the number 
of subscribers !

so the single message is much bigger than it would 
be!
the right message is circa 30Kb,
the resulting sent message is 6-7-
13 MB !
containing hundreds of same txt attachment.

has anyone 
experienced this problem ?
can be caused by an high number of 
subscribers ?

thanks in advance,
bye.
