Email messages sent from my office (from anyone’s computer) to my home address are not getting to either my home ISP webmail or my home PC. Messages do appear in the “Sent” folder at origin.
However, if I access my company’s webmail system and send a message home, it does arrive. Mail sent via my Blackberry also arrive.
Anyone care to venture a guess?
There’s not enough info here to diagnose but here’s what comes to mind:
Possibility 1: Email messages sent from your office don’t go anywhere. Have you checked this?
Possiblity 2: Your ISP for some reason may be filtering email from your company’s SMTP server(s) as spam. Mail sent by webmail or Blackberry may use different servers/IP addresses that are not filtered. Have you checked with your ISP?
Your office webmail probably uses the same SMTP server as your office computer does (but it might not, CookingWithGas is right)…but the originating COMPUTER may be the problem.
If you send from a computer, mail headers will say something like “Received from SanDiegoTimComputer[your.office.computer.IP] by your.office.smtp”. If you send from webmail, it’ll say “received by office.webmail.server[your.office.webmail.IP] by your.office.smtp”.
Your office computer may have been compromised at some point and sent out spam from its IP address. You may have also broken some rules, according to your ISP, when sending stuff like emails with lots of recipients or sending out too many emails to the ISP at once.
So, your office computer’s IP may be on your ISP’s blacklist. Your ISP’s postmaster should be sending back some info on why it was blocked, but not all do.
You’ll need to talk to your office’s email system administrator and have them check the logs to see what path this email is taking and what your ISP is responding. If the email logs say it’s been sent, then you need to talk to your home ISP and ask them why you’re being blocked.
