Hi All

I'm very new using Carbonio, I Have couple problem with smtp when my other system send email using SQL,

1.if Set port 465 i have error 

Jun 12 09:59:52 mail postfix/smtps/smtpd[1057024]: connect from unknown[103.109.195.38]
Jun 12 09:59:52 mail postfix/smtps/smtpd[1057024]: SSL_accept error from unknown[103.109.195.38]: lost connection
Jun 12 09:59:52 mail postfix/smtps/smtpd[1057024]: lost connection after CONNECT from unknown[103.109.195.38]
Jun 12 09:59:52 mail postfix/smtps/smtpd[1057024]: disconnect from unknown[103.109.195.38] commands=0/0

2. if I set port 587 ssl i have error :

Jun 12 10:02:12 mail postfix/submission/smtpd[1061318]: SSL_accept error from unknown[182.253.20.148]: -1
Jun 12 10:02:12 mail postfix/submission/smtpd[1061318]: warning: TLS library problem: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol:ssl/statem/statem_srvr.c:1685:
Jun 12 10:02:12 mail postfix/submission/smtpd[1061318]: lost connection after STARTTLS from unknown[182.253.20.148]
Jun 12 10:02:12 mail postfix/submission/smtpd[1061318]: disconnect from unknown[182.253.20.148] ehlo=1 starttls=0/1 commands=1/2

 

3. if I set Port 587 without ssl, I have error

Jun 12 10:04:38 mail postfix/submission/smtpd[1061318]: NOQUEUE: reject: RCPT from unknown[182.253.20.148]: 554 5.7.1 <unknown[182.253.20.148]>: Client host rejected: Access denied; from=<vendor.support@nasionallife.co.id> to=<vendor.support@nasionallife.co.id> proto=ESMTP helo=<BODEV>
Jun 12 10:04:38 mail postfix/submission/smtpd[1061318]: lost connection after RCPT from unknown[182.253.20.148]

 

4. every time i change my /opt/zextras/common/conf/main.cf, the old config always coming back after reload postfix, example, i just commenting some line, after reload the commenting line is back in main.cf. 

sender_canonical_maps =
smtpd_tls_received_header = yes
always_add_missing_headers = yes
lmtp_connection_cache_time_limit = 4s
smtpd_tls_mandatory_exclude_ciphers = aNULL, eNULL, EXPORT, DES, MD5, PSK
smtpd_tls_exclude_ciphers =
#smtp-slow_destination_recipient_limit = 2
#smtp-slow_destination_rate_delay = 5s
#smtp-slow_initial_destination_concurrency = 2
#smtp-slow_destination_concurrency_limit = 2
smtpd_discard_ehlo_keywords = chunking
smtp-slow_destination_recipient_limit = 2
smtp-slow_destination_rate_delay = 5s
smtp-slow_initial_destination_concurrency = 2
smtp-slow_destination_concurrency_limit = 2

is everybody know why the old config is always replace after reload, and where is the default main.cf?

Hi,

Add your third-party Veeam server address to the trusted network by following:

  1. You can do it from Admin GUI.
  2. From CLI:
carbonio prov ms mail.example.com zimbraMtaMyNetworks '127.0.0.0/8 [::1]/128 10.2.5.0/24 veeam_server_ip/32'

Restart services in both cases.

BTW,

  1. do the external server use any username/password to send emails?
  2. If it is not needed then, I would recommend to use 10.2.5.x/32(your server ip) instead of 10.2.5.0/24 as this is considered as best practice to avoid exploitation.

Then try again and let us know.

Happy New Year 🎉

Hi,

Thank you for your response. I have followed the steps to add the third-party Veeam server IP to the trusted network via zimbraMtaMyNetworks. However, we are still encountering a TLS Library Error when the MOFA Veeam server (from their public IP 202.45.145.182) tries to connect to our organization on port 587.

As I mentioned earlier, this third-party server is outside our network, and the request originates from their public IP. Below, I have attached all the relevant logs for your reference.

Could you please assist in resolving this TLS issue? Let me know if further configuration is required on our end.

Thanks again, and Happy New Year! 🎉
