ContributionsMost RecentMost LikesSolutionsRe: EMAIL not going out from emClient It looks like the email client has recommended a solution that works, and appears to be working now. One of the options in the SMTP setup is "Use SSL on a special legacy port". I'm not sure what the means, in detail, but it worked when changed. Thanks for everyone's help and for your patience with my ignorance. Re: EMAIL not going out from emClient Here is the specific error message text: Blacklisted by Internal Reputation Service.

I have another email account, from another domain, in the same client with exactly the same settings and everything works fine for that one. And the client (emClient) has a 'diagnose and troubleshoot' function and it validates connectivity for the working domain and shows it failed for the hughesnet domain. Everything the same. Having said that, I am working with both the client developer (they are slow to respond) and with HughesNet to try to sort this out. Remains baffling unless it has something to do with this blacklist thing. Re: EMAIL not going out from emClient NEW INFORMATION: I logged in via webmail and when I tried to send an email I get an error message back saying: Blacklisted by Internal Reputation Service. and a lot of details stuff about return path after that. No email client involved. Could this be why client has been unable to connect? I am looking into how to resolve this but any suggestions on shat to do? Re: EMAIL not going out from emClient Yes, I have done that, as I said I would. And have started working with them. Re: EMAIL not going out from emClient I have changed the ports as indicated and ensure the authentication is correct. and tried all flavors of SSL. None of it works. Can someone post the "correct" settings (or at least the options) of Ports and SSL on/off for POP mode? I think I have tried every combination. This has worked for 20 years and then ... boom. Re: EMAIL not going out from emClient Now set as you state - still not working. Seems like all combinations of ports and SSL enabled/disabled do not send. What is the proper setting for PORTS and SSL? I operating in POP mode. This has worked for nearly 20 years and all of a sudden .. boom. Re: EMAIL not going out from emClient UPDATE Bypassed my satellite connection and sent using emClient via a smartphone hot spot - and, voila, it worked fine. So it is either being blocked going out by my HughesNet satellite modem, or something with the satellite delay is affecting it. Doubtful it is the delay as other email accounts/servers work fine through the same modem. Thoughts? Re: EMAIL not going out from emClient I tried those port settings with and without SSL. Same errors. Also posted on emClient support page. Baffling. Is there anything else that can be affecting hughesnet server connection? Same email client works for gmail and for another domain (all going through my satellite connection). and I can send/receive hughesnet email from cell phone and webmail. Definitely email client and hughesnet send only related. Re: EMAIL not going out from emClient these error messages: both with and without SSL security enabled 8:13:31 AM "Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond." 8:13:31 AM at MailClient.Protocols.Smtp.SmtpSendCommand.Connect(WorkerStatus status) 8:13:31 AM at MailClient.Protocols.Smtp.SmtpSendCommand.Execute(WorkerStatus status) 8:13:31 AM at MailClient.Commands.Command.Process(WorkerStatus status) Re: EMAIL not going out from emClient I will do that. Although emClient works fine for other non-hughesnet accounts, which seems to eliminate emClient as the culprit. I will, however, include it there.
