Hi,

I've done a fresh installation and everything works well through web email to hotmail, gmail and my company's email. However, when I use outlook to send email. The following error comes up in /var/log/mail.log.

postfix/submission/smtpd[5253]: warning: TLS library problem: error:1408F119:SSL routines:ssl3_get_record:decryption failed or bad record mac:../ssl/record/ssl3_record.c:469:

I've also went through the letsencypt installation and SSL works fine to my knowledge.

Any help would be greatly appreciated.

Thanks.

Re: TLS library problem (only for outlook)

This error is more like a client issue, like it requested in wrong / unsupported (by server) ssl protocol version, e.g. SSLv2, SSLv3. Usually it's safe to ignore.

- Does Outlook report any error?
- can Outlook successfully retrieve and send email?
