RE: remove blat header info?

We use an old version of blat.exe that has the following option:

 

-noh2           : prevent X-Mailer header entirely

 

Is that no longer supported?

Will have to check into that as well LOL

Blat v2.6.2 was not compiled in 64-bit mode, so it reports Win32 in the X-Mailer: header.  Updating your copy of Blat to version 3.2.17 (64-bit) will change the header line to show Win64 instead.  Updating to the latest release will not lose any of your functionality, but will solve problems with Unicode characters such as the French accented é.  Version 2.6.2 has a known problem with a pointer and memory leak.

 

About the X-Mailer: header --- since Blat cannot receive / display emails like Outlook or Thunderbird or The Bat!, anyone knowing that you use Blat to transmit emails is not a concern about some attack vector.  Blat does not stay resident, nor does not listen on any ports for incoming traffic (except from the connected SMTP server), therefore cannot be hacked into from outside.  Some malicious hacker would have already gained access to your network and servers before ever coming into contact with Blat.

 

At present, there is no command line option to disable the X-Mailer: header.  This is something that can be added, if need be.
