If 2011 began with two awards, the 2012 was even more generous leading Libra Esva to first place overall ranking in the highly respected Virus Bulletin Spam test!
After four second places Libra Esva finally achieved the highest final score in a particular edition of the test for both number of competitors (as many as 22!) and type of spam; this is traditionally a very active time for spammers who launch new spam campaigns over the Christmas and New Year holidays!
The first place has been achieved not only for the exceptional ability to block spam (99,96%), but more importantly the lack of false positives!
Numbers are very impressive: Libra Esva missed only 62 messages out of 152,236 scanned emails with 0 false positives!

Fighting “Postmaster@” Spam with Libra Esva |
|
Non ci sono traduzioni disponibili.
 A real headache for almost all IT managers when discussing spam problems is postmaster@ spam. The commonest thing we hear time and time again is
 We are getting spam from postmaster addresses and we don’t know why.
This problem has a multitude of variations and is generally labeled as “postmaster@ spam”.
Simply put, postmaster spam is any spam email that has a postmaster email address, either as a sender or recipient , and whether it is the postmaster for your own domain or for someone else’s domain.
A little background information may be useful here. The postmaster address performs a critical role in email communication and its presence and use is prescribed in the RFCs for the SMTP protocol. The RFC 2821 - Simple Mail Transfer Protocol reports:
“Any system that includes an SMTP server supporting mail relaying or delivery MUST support the reserved mailbox “postmaster” as a case-insensitive local name.”
…and…
“SMTP systems are expected to make every reasonable effort to accept mail directed to Postmaster from any other system on the Internet.”
