Pop3MessageInfo.Size always returns -1

Hi, I have the following problem, I try to get the size of the mails and I always get -1, try the GetMessageSize method, but in the same way I always get -1, is there any other way to get it?

Hello @fvillanueva,

Thank you for sharing your problem.

It can arise from the mail server’s capabilities that is used for connection via POP3 client.

Do you use a public mail server (like Gmail, etc.) or else?

Thank you.

Hello Margarita

Well, we use our own email server

Hello @fvillanueva,

We’d be happy to help you with the problem. For this, we suggest creating a test account on your server to reproduce the issue on our side. If you can do it, we’ll make the post private.

I have changed from POP3 to IMAP, with this protocol there is no problem

Thank you very much

@fvillanueva,

It’s good that you found the way out.

If you have any other questions please feel free to ask.
