farmeunit Posted April 7, 2013 Share Posted April 7, 2013 What do you mean by "none of the authentication methods supported by this client are supported by your server"? What server are you trying to connect to? What firewall are they using at work? Is it blocking outbound traffic? Check to make sure ports are open?

ReMad Posted April 7, 2013 Author Share Posted April 7, 2013 nothing changed on any configuration in the company POP3 mail hosted outside the company yes checked all ports , ip , name if blocked all are Ok it seems an issue with the ISP as when connecting from other ones we dont see the problem what I need to check from ISP side ?

+BudMan MVC Posted April 7, 2013 MVC Share Posted April 7, 2013 "Receiving is fine" Which would be pop, do you mean you can not send mail? What are you setting for sending? Are you trying to send via just smtp with auth before, are you trying to use TLS to auth? What company are you using for outside email services? Its quite possible if your trying to send via smtp (port 25) that your isp is blocking that - many isps block 25 outbound from their network. winrez 1 Share Link to comment Share on other sites More sharing options...

+BudMan MVC Posted April 8, 2013 MVC Share Posted April 8, 2013 Its like pulling teeth with tweezers getting anything to work with around here. What company are you using for email so we can look up the setting for them, what settings are you using? Are you even using 25 to send? Maybe your on 587 or something if your using TLS? Why don't you just drop to a cmd prompt and test and see what error you get when talking to the email server to send email? Link to comment Share on other sites More sharing options...

+BudMan MVC Posted April 9, 2013 MVC Share Posted April 9, 2013 Didn't do anything, but your welcome I guess. So yet another issue with no root cause found, but without any info to work it wasn't looking good anyway. xendrome 1 Share Link to comment Share on other sites More sharing options...
