I have seen posts about this error when sending to multiple recipients, but I am only sending to one. This is a new installation of Mailenable Standard, I am able to log on using my email account (either through webmail or from an email client) and I am able to send email FROM that account, but when...

All problems solved. Changed the SMTP port back to 25 but set the Alternate Port to Listen On to 587...worked like a charm!

Okay, now it looks like nobody is able to receive e-mail through MailEnable. I ran the diagnostics and the Inbound SMTP Bindings Test shows "Warning - No SMTP Server was detected at this IP Address." Could changing the port do that? I'm still able to Telnet in to the new port, 587. Please help!

Progress! Since the router didn't appear to be getting my requests I wondered if by any wild chance my ISP was blocking port 25...did a Google search on it and sure enough, they do, the rats. So I changed the SMTP port in MailEnable to a different one and am now able to connect via Telnet. I'm still...

Correction, the router log does NOT show my attempts to get in on port 25, it DOES show attempts on port 110

Hi Ian, I use MS Security Essentials on the server, which doesn't seem to have a specific e-mail scanner. I did try turning off "real-time protection", but it didn't make any difference. DId you connect with Telnet using port 25? I went through all the MailEnable options I could find that might have...

No luck, I disabled it on both the remote and the server and still couldn't connect.

Hi Ian, thanks for responding. Telnet from the remote Windows 7 machine fails: "Could not open connection to the host..." Telnet from a machine on the local network succeeds. Telnet from the remote machine to a different port (FTP - 21) succeeds. I checked the port forwarding on the router and it is...

I am trying to set up Windows Live Mail on Windows 7 to access our MailEnable server from a remote location. I can receive e-mail fine, but cannot send. I am using the exact same settings as a local computer, which can send fine. The SMTP logs do not show any activity from my remote location. The er...

Thanks for your response, Ian. I upgraded to 4.26 and that seems to have taken care of the problem.

Hi, I saw some posts that showed this as a problem with older versions of MailEnable but none with version 4.0. When receiving an email with an attachment in Webmail, the attachment does not show up. If I then forward that e-mail to my other account and receive it in Thunderbird, the attachment is t...
