Hello there,
I’m having trouble getting either IMAP or POP3 to retrieve emails in osTicket. We have an in-house hosted Exchange Server that uses TLS encryption on the standard ports.
I’m able to connect from the osTicket server to our Exchange server using openssl commands:
openssl s_client -crlf -connect exch_server:143 -starttls imap
openssl s_client -crlf -connect exch_server:110 -starttls pop3
Once connected I can send all the standard POP3 and IMAP commands for listing retrieving mail etc.
I’ve tried using tls;//exchange_server in the host field and get an error “Can’t Enable TLS”.
Outgoing SMTP works fine.
