Re: ISP blocking port 25, how to send mail from Iseries

[John Ross <jross-ml@xxxxxxxxxxxxxxx>]

After reading http://news.zdnet.com/2100-3513_22-5230615.html  I 
understand what they are doing.

If your IP addresses is static maybe your mail ISP will allow relaying. 
You might also want to look at javamail.

I would be surprised if mail1.myisp.com:587 would work, I would think 
you would have to change SMTP with  WRKSRVTBLE
