20101006 - rhsbl.sorbs.net listing all domains
Within the last 90 minutes it appears that the rhsbl.sorbs.net RHSBL has suddenly began listing all domains. As a result, our system, which had previously been using this repuation provider, was suddenly rejecting many incoming e-mails with the following message:
554 Service unavailable; Sender address [user@gmail.com] blocked using rhsbl.sorbs.net; Domains found in URLs in spam See: http://www.sorbs.net/lookup.shtml?gmail.com
The specific domain does not appear to matter.
To correct this problem, the rhsbl.sorbs.net RHSBL was removed from our system at 16:11 CDT.

Q: What is the maximum e-mail attachment size?
A: The ETRN.com e-mail servers do not limit the size of individual e-mail attachments. The ETRN.com e-mail servers do impose a 400 MB maximum total message size limit. Individual customers can choose a smaller message size limit. We can also customize the handling of "over-sized" e-mails. Please contact us to discuss your specific needs. A couple of important facts:
1. Attachments are typically encoded in what is called Base64[1]. As a result, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original file size.
2. E-mails often contain both plain text and HTML components. This also increases the overall size of the e-mail.
