[SOLVED] POP3/IMAP Sending Mail Errors
I’m having the same symptoms as in this post:
http://www.zimbra.com/forums/users/1...g-failure.html but I have not been able to resolve it per the thread. I have checked the wiki mentioned in that same thread, and with that:
My firewall settings show NAT from my public IP to my server with the following services open: POP3 (110, 995), SMTP (25), Web Server (80), HTTPS (443), IMAP (143, 220, 585, 993) Zimbra Mgt (7071) and VNC (5900).
[zimbra@mail root]$ zmprov gs mail.mydomain.com | grep Auth
[zimbra@mail root]$ zmprov gs mail.mydomain.com | grep Mode
I’ve tried configuring Outlook Express but can’t send messages. I receive the following server time out error:
As far as the client set up, I’ve tried both POP3 and IMAP with “outgoing server requires authentication” turned on and off.
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'mail.mydomain.com', Server: 'mail.mydomain.com', Protocol: SMTP, Port: 25, Secure(SSL): Yes, Socket Error: 10053, Error Number: 0x800CCC0F
I can receive messages just fine. Web UI or Outlook Connector users have no issues what so ever.
One other fact is one of my users who is at the Office and behind the firewall sent me an e-mail using Outlook Express without issue.(?)
Any help with this will be greatly appreciated…
Thanks for your help! - Answer To Post
Well your reply in my PM has at least let me know that this is MY issue and not a problem with the server. :)
There is something up other than just my settings for POP or IMAP. I can't telnet to my server on port 25.(?) I keep getting a can't connect message when trying either the domain name or IP address. I think my IP is blocking port 25 unless it goes to their SMTP server. I have heard that Charter/Comcast will do things like that
For me this is not an issue as I use either the web UI on location visits or Outlook on my laptop. All of the users who use OE seem to be working correctly. Having moved to Zimbra 2 weeks ago, I think I would have heard something by now.
I told my DO and VP that we are making a good move in switching to Zimbra and the level of support has proved me correct.
My goal is to learn enough to be able to help someone else. Thanks for taking the time to work with those of us who are still, and never hope to stop, learning.
I'll mark this as solved as this is my issue and not one of my server.
Again, thanks for all your time and help.
