Re: recipient_bcc_maps seem to be ignored in master.cf

This is useless here because recipient_bcc_maps are handled by cleanup(8) and not smtpd(8). You need to use a different cleanup(8) instance which overrides the default bcc maps setting for mail coming through this special smtpd(8) listener. Cool! So i wrote this, and working! Thank you! smtps i

recipient_bcc_maps seem to be ignored in master.cf

Hello! In main.cf I am using a global blind carbon copy table: recipient_bcc_maps = hash:/etc/postfix/global_bcc I would like to ignore this table, when trusted user sends a mail so i wrote this into master.cf: smtps inet n - n - - smtpd -o smtpd_tls_wrap

way to hide the error message reason?

Hello! We are maintaining a couple mail hosts (>100). It's fine, cause they generate low e-mail traffic. Now we got some new domains, and we belive the stress will be excessive, not just bots, but i fear hackers, ddos, etc (but the ham would be still low). To prevent risking the 100 other dom

Re: multiple reverse DNS?

If I have a box with a valid reverse DNS entry of mail.example.com that has virtual domains of domain.com otherdomain.com somedomain.com will my "wrong" reverse DNS for the virtual domains affect delivery? Do I need to do anything? You can simply do the following: domain.com. MX 10 mail.examp

DNS based virtual domains?

Hello! I am maintaining several virtual e-mail domains, and they're growing. I made my own scripts to modify those, in postconf/vmailbox, then issuing postfix reload and postmap is working fine. The mailbox backend is Cyrus over lmtp + i am using address verification, so postfix doesn't know

Re: reject_unverified_recipient check is somewhat slow for local mail

15 seconds? Postfix out-of-the-box waits no more than 9 seconds for the very probe to succeed. Perhaps you have been changing Postfix parameters. Please follow instructions as requested in the mailing list welcome message. Sorry, my bad, I had the address_verify_poll_delay set to 15 seconds, w

Re: reject_unverified_recipient check is somewhat slow for local mail

Postfix logs delays in fine detail including the delays of address probe messages: time in incoming/deferred queue, time in active queue, time to complete DNS lookup and TCP/SMTP/LMTP handshake, time to transmit message. Apr 10 13:02:15 mail postfix/smtpd[24851]: connect from mycomp.mydomain.co

reject_unverified_recipient check is somewhat slow for local mail

Hello! I see a minor glich, doesn't hurt, just would like to know what causes it. I am using Postfix + Cyrus, using unixsocket-LMTP transport. I am using address verification for local destinations too (Postfix doesn't know about the cyrus users, so it uses the LMTP to discover a user, and reac

Re: Accepting sender with MX _only_

can you show an example? postfix log (my contract forbids to put client data here, so masqueraded the real hostnames and IPs): Mar 6 19:01:41 mail postfix/smtpd[6930]: NOQUEUE: reject: RCPT from www.XXX.hu[X.X.X.X]: 450 4.1.7 : Sender address rejected: unverified address: connect to www.XX

Accepting sender with MX _only_

Hello! I don't need to say, if your server is popular, you'll get a dozens of spam too. Lately i am getting random mails from www-d...@www.some.hackedsite.com . I am using address verification, so they usually not coming in, cause port 25 is not open on www.some.hackedsite.com (no MX record o

Address verification question

Hello! I am using Address verification now with ~90% success (using it over a year now). The only flaw i didn't find a solution yet is the following: When a server rejects an e-mail address with 5xx, mine rejects it only with 4xx. But! I would like to reject them with 4xx if the foreign ser

Multiple PTRs

Hello! (sorry for my trash-english) Will Postfix handle properly multiple PTR records when reject_unknown_client_hostname is in effect? Like would it accept an e-mail when it comes from 1.2.3.4 and 2001::1234:2 if smtp_helo_name is mail.example.com when the DNS records are the following?
