In general, you can certainly send ZIP files to GMail. Also, what >was the size of those attachments? The e-mail used as sender address >didn't get any SMTP error message, did it? Personally, I'd guess for >some other difference in your sending apart from the attachment type. It is not a size problem, the test mail contains just a very small zipfile sample (5 kb in size). And the mail is not in the spam folder either, it is simply silently rejected by GMail... No error message. It turns out that GMail inspects the *content* of the zipfile and if it discovers "dangerous" constituent files it blocks delivery altogether. https://support.google.com/mail/answer/6590?hl=en#zippy=%2Cmessages-that-have-attachments%2Cmessages-that-dont-have-attachments In my case there is a small text file inside named <something>.cmd which is NOT a Windows command file (similar to a batch file) but a file with a set of equipment commands and geometry information.... So I tested by changing the extension from .cmd to ,cmd.txt and then delivery started working... So now I have to modify the automatic server so it will rename this particular file using a different extension. But that is easier than dealing with the OpenSSL incompatibility of Indy10 in any case. -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
