Many people use fax2email services these days. Some use the pdf format, more the FaxTIFF, supported in the multi-page-version by WarpTIFF.datatype on the Amiga. Viewing multiple pages requires the program using the datatype to split it. The author of WarpTIFF offers a program called SplitMultiImage which should do the job if you could integrate some GUI elements to operate the whole thing. Would be a great help...
I really like SimpleMail now - it is fast GUI-wise as well as mail-transfer-wise, and quiet robust. Thanks for your work!!!
