I have issues with sending mail from Manager. I use the Linux version on Ubuntu 20.04. The error message when setting up the smtp account is: Message could not be sent.
When trying to send a mail from within the invoice i get:
System.IO.IOException: System.IO.IOException: Unable to read data from the transport connection: Connection reset by peer. ---> System.Net.Sockets.SocketException: Connection reset by peer at System.Net.Sockets.Socket.Receive (System.Byte buffer, System.Int32 offset, System.Int32 size, System.Net.Sockets.SocketFlags socketFlags) [0x00016] in :0 at System.Net.Sockets.NetworkStream.Read (System.Byte buffer, System.Int32 offset, System.Int32 size) [0x0009b] in :0 --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read (System.Byte buffer, System.Int32 offset, System.Int32 size) [0x000e2] in :0 at Mono.Net.Security.MobileAuthenticatedStream+<>c__DisplayClass85_0.b__0 () [0x0002b] in :0 at System.Threading.Tasks.Task`1[TResult].InnerInvoke () [0x0000f] in <6649516e5b3542319fb262b421af0adb>:0 at System.Threading.Tasks.Task.Execute () [0x00000] in <6649516e5b3542319fb262b421af0adb>:0 --- End of stack trace from previous location where exception was thrown --- at Mono.Net.Security.MobileAuthenticatedStream.InnerRead (System.Boolean sync, System.Int32 requestedSize, System.Threading.CancellationToken cancellationToken) [0x00104] in :0 at Mono.Net.Security.AsyncProtocolRequest.InnerRead (System.Threading.CancellationToken cancellationToken) [0x000ac] in :0 at Mono.Net.Security.AsyncProtocolRequest.ProcessOperation (System.Threading.CancellationToken cancellationToken) [0x00093] in :0 at Mono.Net.Security.AsyncProtocolRequest.StartOperation (System.Threading.CancellationToken cancellationToken) [0x0008b] in :0 at Mono.Net.Security.MobileAuthenticatedStream.AuthenticateAsClient (System.String targetHost, System.Security.Cryptography.X509Certificates.X509CertificateCollection clientCertificates, System.Security.Authentication.SslProtocols enabledSslProtocols, System.Boolean checkCertificateRevocation) [0x0004b] in :0 at System.Net.Mail.SmtpClient.InitiateSecureConnection () [0x00059] in :0 at System.Net.Mail.SmtpClient.SendCore (System.Net.Mail.MailMessage message) [0x000a0] in :0 at System.Net.Mail.SmtpClient.SendInternal (System.Net.Mail.MailMessage message) [0x00050] in :0 at System.Net.Mail.SmtpClient.Send (System.Net.Mail.MailMessage message) [0x00084] in :0
The smtp setup and credentials are correct because on Win10 version is have no issues.
I mentioned this issue in another thread but since it seems a linux issue only i start this new one. I would like to know if there are other linux (ubuntu) users which experience same issue.
The issue is easy to replicate, you only need a clean install of ubuntu 20.04 (or 18.04) and test the sending of the mail.
If i am the only one with this issue, i rest my case and move on to another solution but as a long time user of Manager i would like to keep using it.
