Hi, I've got a problem with my mail server in that any 'CC' or 'BCC' email is not being delivered. The sever is running virtual mail setup with: - Debian Sarge - 2.4.27 smp kernel - courier 0.47-4 courier-pop, courier-imap, courier-authmysql - postfix 2.1.5-0 postfix-mysql, postfix-tls - maildrop 1.6.3, maildropmysql - spamassassin - clamav 0.88.2 - amavisd Basically, if someone sends an email (from anywhere) to an email address on my server, and also CC or BCC an email address on my server, it gets delivered to the person in "To:", but not to "CC" and "BCC. Eg: Consider the following 3 people - PersonA with an external address: [email protected] - PersonB with address on my server: [email protected] - PersonC with address on my server: [email protected] Suppose PersonA sends the following email: To: [email protected] CC: [email protected] Subject: foobar Message: test [email protected] receives the email successfully in their inbox. However [email protected] doesn't, nothing arrives, seems the CC email disapears. I get the following extract in my mail log: Code: Jul 7 14:12:10 aqua postfix/qmgr[31036]: 44C6554EAA: from=<[email protected]>, size=3280, nrcpt=2 (queue active) Jul 7 14:12:10 aqua amavis[8578]: (08578-04) ESMTP::10024 /var/amavis/tmp/amavis-20060707T140450-08578: <[email protected]> -> <[email protected]>,<[email protected]> Received: SIZE=3280 from aqua.xxx.co.nz ([127.0.0.1]) by localhost (aqua [127.0.0.1]) (amavisd-n ew, port 10024) with ESMTP id 08578-04; Fri, 7 Jul 2006 14:12:10 +1200 (NZST) Jul 7 14:12:10 aqua amavis[8578]: (08578-04) Checking: <[email protected]> -> <[email protected]>,<[email protected]> Jul 7 14:12:11 aqua amavis[8578]: (08578-04) spam_scan: hits=0.087 tests=HTML_40_50,HTML_MESSAGE Jul 7 14:12:11 aqua amavis[8578]: (08578-04) FWD via SMTP: [127.0.0.1]:10025 <[email protected]> -> <[email protected]>,<[email protected]> Jul 7 14:12:11 aqua amavis[8578]: (08578-04) Passed, <[email protected]> -> <[email protected]>,<[email protected]>, Message-ID: <0 01f01c6a16a$c5c1de20$4503a8c0@Mike>, Hits: 0.087 Jul 7 14:12:11 aqua postfix/smtp[8931]: 44C6554EAA: to=<[email protected]>, relay=127.0.0.1[127.0.0.1], delay=1, status=sent (250 2.6. 0 Ok, id=08578-04, from MTA: 250 Ok: queued as 17E4454EB6) Jul 7 14:12:11 aqua postfix/smtp[8931]: 44C6554EAA: to=<[email protected]>, relay=127.0.0.1[127.0.0.1], delay=1, status=sent (250 2.6 .0 Ok, id=08578-04, from MTA: 250 Ok: queued as 17E4454EB6) Jul 7 14:12:11 aqua postfix/qmgr[31036]: 44C6554EAA: removed Jul 7 14:12:11 aqua postfix/pipe[8936]: 17E4454EB6: to=<[email protected]>, relay=virtual, delay=0, status=sent (xxxxx.co.nz) Jul 7 14:12:11 aqua postfix/pipe[8936]: 17E4454EB6: to=<[email protected]>, relay=virtual, delay=0, status=sent (xxxxx.co.nz) Jul 7 14:12:11 aqua postfix/qmgr[31036]: 17E4454EB6: removed Its the same with CC and BCC emails, and the same if the sender address is from an external address, or an internal address on my server. Anyone experienced this, or something similar where CC/BCC emails don't get delivered? One thing to note, is that if an email like the following is sent (internal user sends to external user, and CC's to internal user), then it works fine: From: [email protected] To: [email protected] CC: [email protected] Subject: foobar ...
But the mails have been sent: Does [email protected] maybe point to the same mailbox as [email protected]?
No, they are completely seperate mailboxes. I just did another test, and it seems its not just CC/BCC mail, its any mail delivered to 2 or more mailboxes on my server. Eg, if [email protected] sent an email with headers: To: <[email protected]>, <[email protected]> Then only [email protected] receives the mail, not b@myserver Its weird that in the 1-2 years I've had this server running, I never even noticed this fault!! Bugger! So any email sent to more than 1 person on my server, only the first person received it, no one else. Its weird cause in the log, the emails have the same ID, eg: 17E4454EB6
Hi, ok here is my postfix config: transport.cf: Code: user = postfix password = ******** dbname = xxxxx table = email_domains select_field = transport where_field = domain hosts = 127.0.0.1 aliases.cf: Code: user = postfix password = ******* dbname = xxxxx table = email_addresses select_field = maildir where_field = email hosts = 127.0.0.1 remote_aliases.cf: Code: user = postfix password = ********* dbname = xxxxx table = email_aliases select_field = remote_address where_field = email hosts = 127.0.0.1 And here's the end of my main.cf file: Code: myhostname = aqua.xxxxx.co.nz myorigin = /etc/mailname alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases program_directory = /usr/lib/postfix mydestination = mail.xxxxx.co.nz, aqua.xxxxx.co.nz, aqua, mail.xxxxx.co.nz relayhost = transport_maps = mysql:/etc/postfix/transport.cf virtual_mailbox_base = / virtual_uid_maps = static:1001 virtual_gid_maps = static:1001 virtual_mailbox_maps = mysql:/etc/postfix/aliases.cf virtual_maps = mysql:/etc/postfix/remote_aliases.cf qmgr_message_active_limit = 100 qmgr_message_recipient_limit = 100 content_filter = smtp-amavis:[127.0.0.1]:10024 message_size_limit = 51200000 unknown_local_recipient_reject_code = 450 smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = $myhostname broken_sasl_auth_clients = yes Can you see anything wrong with my config, or anything that might suggest why emails aren't being delivered to the 2nd, 3rd... addressed users when sent to multiple users? I can provide more of the main.cf file, or other files, just let me know what parts. Thanks, Mike
Ok, you have all your data in a MySQL database, so you should check the MySQL database if there's some problem with the data (aliases, transports, etc.) that causes your problem.
The MySQL database seems fine. All of the data seems fine, and if manually run queries based on those that postfix is using (to get transport, aliases, and remote_aliases, they all return data ok. And as the mail server has been handling email perfectly ok for 1 person in the "to" field, then the database seems to be fine. Maybe its something else? Amavis, or maildrop?
Ok, finally found a part solution!!! Seems other people have had this problem too. In the maildrop README.postfix file, I found this: Ok, so I added the "maildrop_destination_recipient_limit = 1" line to my postfix main.cf file. Then reloaded postfix, tested by sending email with multiple recipients, and it didn't work. So I tried something different, turning off content filtering (spam/virus filtering with clamav, spamassassin, via amavisd). I did this by commenting out this line in main.cf: Code: #content_filter = smtp-amavis:[127.0.0.1]:10024 Then reloaded again, tested, and YAY it worked! It was correctly delivering to all recipients!!! So, why I wonder does it not work when the "content_filter" is turned on? Only when its off? Thats the next thing I'll have to find out. I can't leave the content-filter off, as its removes on average 500 spam and 10 virus emails every day! Mike
Well after further testing, I found that in fact 99% of mail is now working correctly! With content-filter turned on. The only thing that isn't working with 'content-filter' on, is if I send an email like the following: From: external address To: [email protected] CC: [email protected] Eg, if I send an email to the same person, in 'To', and 'CC'. Or the same person in 'To' twice. Or if I send to [email protected] and an alias (eg [email protected]) that forwards to the same address, [email protected] But I'm thinking thats how mail servers are supposed to work? If an email is addressed to the same person more than once, it only delivers it once. That was were I was getting the problem above, i was sending email to myself, and an alias to myself. All other mail now works fine!! So the amavisd content filter is working. Thanks falko for your assistance! Hopefully this helps someone else, if they have the same issue.
