[opensuse] Disappearing mails
Hi, I have a postfix-server, with some precautions for malware. Most mails arrive without problems but recently, users are complaining about mails not arriving. When the mail is expected and when asked for it (telephone), the copy arrives OK. So it's not always the same sender(-domain). I checked the logs of postfix, nothing to see. My firewall (Watchguard) does also check for malware. I checked those logs also. Again, nothing to see. For incoming mails, my server listens to the "open internet" (I think, maybe the ISP proxies ? I'll ask). Any suggestions what I can do to investigate further ? Or can I just say it's not our fault ? Sometimes I do see a connection attempt from a ligitimate sender, but after 5 minutes, the connection interrupted because there is no data. Any explanation ? I'm very puzzled. TIA, Koenraad. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Assuming they mail again. Instead, if they got a failure message from their isp, and could forward it to you, then you'd have something to go on. If postfix decides not to accept an email, I'm unsure it always logs it. - -- Cheers / Saludos, Carlos E. R.
