JavaMail and spam
Posted on 2011-03-03
Hi,
I have upgraded java mail to version 1.4.4. And i notice that my messages are recognized as spam.
Normal sending is ok, but clone of message dont.
I do something like:
MimeMessage newMsg = new MimeMessage(org_msg);
newMsg.setRecipients(Messa
newMsg.setRecipients(Messa
newMsg.setRecipients(Messa
newMsg.saveChanges();

Usually in Spam-Marked Mails you can see a comment of the filter telling you exactly why the mail was treated as spam.
Did you have a look at this? If not I doubt we can guess the reason for this.

Well I guess having a look at this, it seems that the mime-encoding set in the header is not set or incorrect and the ip-address sent in the HELO command of the SMTP connection is wrong (if the remote server uses the name provided by the HELO to lookup the IP of the sender and this check fails). This usually happens when your sending server has local names and ip-addresses (it is inside a local network which accesses the internet via NAT or a Proxy).
From the 4th response your server is propably sending it's local IP adress, which the recieving host cannot access.
Iam not responsible for making mails. Java mail do this. Iam interested why changing java version make mail spam
Well I think the problem is that your Application is sending emails. And naturally your machine is posting it's local IP address in the EHLO SMTP command (Lets say you have the local ip 10.10.10.123) If you now use a Gateway (10.10.10.1 with the ip 1.2.3.4 from the Internet) then the remote Server will recieve an EHLO from the IP 1.2.3.4 but will say that he's 10.10.10.123 in the EHLO. This is the reason for your spam-rating.
I think the best solution (The one I allways use) is to use your fully configured company mailserver, create a dedicated account for your application (or a shared one to support all your applications) and to make the SMTP Server relay the mails to the final destination ... this way you should no longer have these problems.
