Such a problem is not always within your own system. Among other causes: * The recipient's mail host might block the message because the recipients inbox is full, because your ISP was (erroniously?) identified as a source of spam, or because a possibly innocent attachment to your message violates some policy. I have seen this happen. Worse, I have seen this happen when the recipient's mail host is not configured to issue a bounce message. * Your own ISP's mail server blocked the message because of an attachment that is a file-type it does not allow. I once used an ISP that would not allow me to send an application (file-type .exe) as an attachment. It also prevented me from sending ZIP files. Both of these were considered sources of malware. Again, I got no response message that my E-mail did not go through. (In the case of an application, I would zip it; for that and other ZIP attachments, I would then remove the file-extension, My E-mail would instruct the recipient to restore the .zip extension and then unzip it.) -- David E. Ross <http://www.rossde.com/> President Trump claims there would have been no victims in the Pittsburgh synagogue if there were armed guards inside. He ignores the fact that there were two police officers already in the facility, armed with their service weapons, before the shooting started. The problem of mass shootings cannot be solved by having even more guns. _______________________________________________ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
