Re: [Phpmailer-general] Newbie: Filesize > 1.5MB = "Could not instantiate function"

[James B. <stu...@gm...>]

SOLVED

Imagine that! The answer here, as in other places, is to adjust the maximum
message size ... in the SMTP program.

Here's how I did it with Microsoft IIS7 SMTP:

1) You MUST use IIS6 Manager to adjust your SMTP settings ... even though
it is included with IIS7 (as an extension from the Exchange team, not the
MS web server team), IIS7 does not have any mechanism to do adjust it!
Brilliant, MS!

2) Open IIS6 Manager

3) In the left column: Select the system you are modifying

4) In the right column: See "[SMTP Virtual Server #1] => Running"

5) Right-click "[SMTP Virtual.." and select "Properties"

6) Under the "Messages" tab, check the value of "Limit message size to
(KB):" Mine was set to 2048.

7) Increase that value to what you need. I went up to 20MB (20480 KB)

8) Also increase the value of "Limit session size to (KB):" so it is larger
than "message size". I went to 40MB (40960 KB).

Bingo.

Thanks for your thoughts, Chris.
