Hi, my sendmail seems to avoid receiving mails unencrypted, and that actually makes me lose a lot of mails I need.
This is an example from my logfiles: (I changed the IPs and hostnames to examples)
Code:
Jan 9 05:56:09 paron-02 sm-mta[14974]: j094u8su014974: ruleset=check_mail, arg1=<info@example.net>, relay
=xyz.example.com [111.111.111.111], reject=403 4.7.0 encryption too weak 0 less than 128
Jan 9 05:56:09 paron-02 sm-mta[14974]: j094u8su014974: from=<info@example.net>, size=3249, class=0, nrcpt
s=0, proto=ESMTP, daemon=MTA, relay=xyz.example.com [111.111.111.111]
Where in sendmail.mc is this controlled? I don't think access.db is involved, that's why I don't post it.
Here's my sendmail.mc:
Code:
divert(0)dnl

Well, I cannot find the line I have to change reading the sendmail configuration guide, so I'm asking here; tia
Edit:
Forgot to mention; when I fetch mail using fetchmail, I get the same Error (SMTP Error 403) "encryption too weak 0 less than 128" , no matter if I fetch mail from my own server or from a public ISP.
