we have multi-server installation with 4 Mailboxd server all of them with POP3/IMAP access ( no webmail )
All its ok until i enable pop3/imap proxy on any server.
When user login with clear text password POP3 on proxy, login its successfully and small mails are downloaded without problems, but random user experiment:
SSL_read() failed (SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number) while proxying and reading from upstream,
SSL_read() failed (SSL: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac) while proxying and reading from upstream,
This logged error cause pop3 session down.
I dont understand SSL Erros on non SSL pop3 Session.
