Sender Email Address Size Limitation?

Hello blat group!

I am using blat 32-bit windows command line, and found that it was failing the smtp authentication to my server (godaddy -- smtpout.secureserver.net:80), and the length of the sender email address was fairly long (42 characters), so I suspected that may have been the problem.

I shortened the length of the sender email address to 33, and had no further problems.

I searched through the source code for array dimensions/constants, and found this declaration in blat.h:

#define SENDER_SIZE             256

...so I figured that the program was designed to handle sender email address sizes up to 256 characters?

Anyone else run into this problem?

Thanks!
