Hell guys,
I’m coding in csharp to send an email which contains a .zip file (has htmls and css inside). When I check the mail recieved, In fact, instead of the .zip file, the attachment becomes a txt file and has:
FILE QUARANTINED
The original contents of this file have been replaced with
this message because of its characteristics.
File name: 'xxxxxxx_Result.zip'
Virus name: 'Large uncompressed size'
The exchange server has blocked the zip file..I’m using CDO to create and send the email.
I tried using the code to send a mail with a zip file generated by WINZIP, there was no problem, then I tried using outlook to send a mail with the zip file generated by my code(I use sharpziplib library), the problem occured…
How can I do to send the attachment correctly? Many thanks in advance!
Allen
I encounter similar problems sending email on our network. I’ve found that using an alternate compression format, such as 7-zip (.7z), is adequate to get my content through the filters. This could resolve the issue if the block is not due strictly to size.
