That FAQ item, referenced as
http://www.e-smith.org/faq.php3#8q36 didn't work here and it still doesn't now:-( I used the figure of 75M (to cope with 66MB picture images). WebMail just bombs out when it attempts to send out locally with a test attachment of 66MB, again at 30MB, again at 16MB and, finally, only starts working with the *smallest* test image of 6MB. OK, I agree, that's bigger than 2MB:-) The FAQ is a little disingenuous to maintain that those two command lines will enable WebMail to send out 50MB attachments on SME5.5 and 5.6. It certainly increases the 2MB limit some... to, I'm guessing here, around 10MB?. FWIW I use SME5.6u2.
best wishes, Robert
