Imap connect on port 993

Question

I try to connect imap with:

Dim ImapClient = New Imap()
ImapClient.Connect("imap.pec.it", 993)

but the system return:
tried to read a line. only '' received. Please make sure that you have disabled antivirus and firewall software or that you have configured them correctly.

Can you help me?
Many thanks.

Answer 1

993 port is for IMAP over SSL (IMAPS).

You need to use Imap.ConnectSSL method. As this is standard port there is no need to specify it. Simply use this code:

Dim ImapClient= New Imap()
ImapClient.ConnectSSL("imap.pec.it")
