Hello everyone, my server works pretty well but I still have some problems sending e-mails. Some of them don't work and end up in time-out. Could this be due to a bad configuration of my ipV6? Do I have to configure it in postfix or can I force ipV4 alone? I put here the return mail that came to me several days after I sent it...

I see the problem for a IPv4 address aswell, so it might be a issue with your network or network adapter.
Hi Thom, thanks… network adapter ? I don't know if I have one I have a scaleway's VPS : Code: Public IP 163.172.143.149 Private IP : 10.65.110.21 IPv6 : 2001:bc8:47b0:170a::1 Gateway : 2001:bc8:47b0:170a:: Netmask : 64 Public DNS : b2ba61ba-757f-4ed3-9f37-4ce915d98047.pub.instances.scw.cloud $ ifconfig : Code: ens2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.65.110.21 netmask 255.255.255.254 broadcast 10.65.110.21 inet6 2001:bc8:47b0:170a::1 prefixlen 64 scopeid 0x0<global> inet6 fe80::dc1c:4cff:fe4b:200b prefixlen 64 scopeid 0x20<link> ether de:1c:4c:4b:20:0b txqueuelen 1000 (Ethernet) RX packets 9839295 bytes 2021996700 (1.8 GiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 9556834 bytes 4678798870 (4.3 GiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 750835 bytes 230961632 (220.2 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 750835 bytes 230961632 (220.2 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Every server has a network adapter if they are connected to the internet. You might want to check with scaleway to see if there is a problem on their end or yours.
Ok, I can try to ask them, but the problem is not with all my mail adresses… Could you please show me where do you see the problem, I will follow… Tanks a lot

For example these two: Code: <[email protected]>: connect to smtp-in.orange.fr[193.252.22.65]:25: Connection timed out <[email protected]>: connect to alt2.gmail-smtp-in.l.google.com[2404:6800:4003:c05::1b]:25: Connection timed out I think your network just times out so it is not related to the mailaddress. Or port 25 is blocked on your network...
simple test. from the cli on your mail server. telnet 193.252.22.65 25 see if that connects or times out. if it times out, try telnet 193.252.22.65 587 if that connects ok, then you have a firewall somewhere blocking port 25 outbound.
Thanks, sounds ok … Code: telnet 163.172.143.149 25 Trying 163.172.143.149... Connected to srv-b.democrasite.com. Escape character is '^]'. 220 srv-b.democrasite.com ESMTP Postfix (Debian/GNU) ------------------------------------- telnet 163.172.143.149 587 Trying 163.172.143.149...

that's your own server. your issue is connecting from your own server to external mailservers. that's why the example i gave was to telnet to the ip address of one of the servers you had problems connecting to: try it again, using the ip in the examples i gave, 193.252.22.65 from the cli of your mail server.
and from scaleway's website: blocking port 25 outbound i can understand, but 465 and 587 as well.... i'm all for paranoia when it comes to server security, but that's a bit excessive.
I don't know how to use cli commands yet. In the PDF manual there is this part : Code: apt-get -y install php5-cli php5-mysql php5-mcrypt mcrypt Do I need to install this?
ermm... you've already used cli commands haven't you? how did you run those telnet tests earlier? although it seems a bit redundant to do them now, since we know scaleways will block them, i assume you didn't make any attempt to enable smtp in scaleways security groups prior to finding this problem?
Yes, I hadn't checked the box for smtp at scaleway. I just did. Earlier for Telnet, I did it with my Terminal Now that scaleway is OK, I'm redoing some tests.
That was the trick I guess… to gmail adresses ; Code: Delivered-To: [email protected] Received: by 2002:a17:906:70c3:0:0:0:0 with SMTP id g3csp3497570ejk; Tue, 27 Oct 2020 04:08:04 -0700 (PDT) X-Google-Smtp-Source: ABdhPJzFaql26PD82scwz52bZTZs5tR9uaU8yG7nC8sXjU/Dy1BgLJWcX4lcAWfDS+UYLTmzs1yF X-Received: by 2002:a5d:4648:: with SMTP id j8mr2164538wrs.131.1603796884023; Tue, 27 Oct 2020 04:08:04 -0700 (PDT) ARC-Seal: i=1; a=rsa-sha256; t=1603796884; cv=none; d=google.com; s=arc-20160816; b=jiUCEKGDxicSGyWY8QsNwJWvQUrr6aH/I3I9c14sLz5UhNCHeGIVQr9zcRUixBsB3t 0dxqla0fXOkC+n7gePkAagGK2lwtsvxXSh3lSRfwMRMnD8YJZ9p3q6k+EtgFCbbJ4Vm4 fnpQhZjGEA5k6q54P9uT9Q5kglL7vUnX3XyrsfUNYyLM8Mef98bD25udfUpyTOQ1/RZf VR13wg3a1MbKvs8I98wGEKx3F+8cC+IrZaZvYsc99QU38BGsG2vhUhv24oMWV1Q4+bEm wovCixLWjzxLcI4kbwyy9gt4Th/msAltELKpWudQzATcnm1/wCvSBjxYfOaAgJ6OOucN zPFA== ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=google.com; s=arc-20160816; h=content-language:content-transfer-encoding:mime-version:user-agent :date:message-id:subject:from:to:dkim-signature; bh=t/EtO3NG3mknuuwPASLpDPnTQB915J8za06TxesA+gA=; b=0s9Q92nCEjwYdb6Pj97dzvcsxR8j315IUmkD1wapGjne9ncAZF6DWVGy8OlPrVojJs vSbXAvzEGq1LqiufmQuqWZRGNe1NYn//sCgoEQPEibEjZDhrXGGo0V2I0YartxkapSh/ pT6wNQUVHMhCrjbR9OgaRWiZZ1C1E8L/DUEuPzCQR5Pj4f508TgSlt3+2/BMCJ1jnEQP HByzYaPO91Y+7F1/VGqAzq0fs44TKbsgfiPpET5AYKey5c+j3RPZexeheOW65TKlBkre n+OgnE2DpBadh4N77hNywV+4Jv8tiatZgNroIdW34YZI3tfXwCZ/NgdmZlNo4nqZENJ8 gN1w== ARC-Authentication-Results: i=1; mx.google.com; dkim=neutral (invalid public key) [email protected] header.s=default header.b=BEIU7955; spf=pass (google.com: domain of [email protected] designates 2001:bc8:47b0:170a::1 as permitted sender) [email protected]; dmarc=pass (p=NONE sp=QUARANTINE dis=NONE) header.from=opaz-ateliers.com Return-Path: <[email protected]> Received: from srv-b.democrasite.com ([2001:bc8:47b0:170a::1]) by mx.google.com with ESMTPS id j12si1276689wmi.61.2020.10.27.04.08.03 for <[email protected]> (version=TLS1_3 cipher=TLS_AES_256_GCM_SHA384 bits=256/256); Tue, 27 Oct 2020 04:08:03 -0700 (PDT) Received-SPF: pass (google.com: domain of [email protected] designates 2001:bc8:47b0:170a::1 as permitted sender) client-ip=2001:bc8:47b0:170a::1; Authentication-Results: mx.google.com; dkim=neutral (invalid public key) [email protected] header.s=default header.b=BEIU7955; spf=pass (google.com: domain of [email protected] designates 2001:bc8:47b0:170a::1 as permitted sender) [email protected]; dmarc=pass (p=NONE sp=QUARANTINE dis=NONE) header.from=opaz-ateliers.com Received: from localhost (srv-b.democrasite.com.democrasite.com [127.0.0.1]) by srv-b.democrasite.com (Postfix) with ESMTP id B810B7FEC8 for <[email protected]>; Tue, 27 Oct 2020 11:08:03 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d= opaz-ateliers.com; h=content-language:content-transfer-encoding :content-type:content-type:mime-version:user-agent:date:date :message-id:subject:subject:from:from; s=default; t=1603796844; x=1605611245; bh=t/EtO3NG3mknuuwPASLpDPnTQB915J8za06TxesA+gA=; b= BEIU7955ZpfK4TZMpSEG0Rrj7P3EjPCnE7l5ONbkGKuJ+n6+rMF3ZoB0u81WJXcG ciuddpqiXE+sSy5gxZ8AJKnvc9OxNrpZ0kjYT3nV0QDL/UmD8e9Z4CjXT3QIQQwn rBBy4fcNNDsJj379nh2DawLWgHKmCGvd0RHU1TyXGB0= X-Virus-Scanned: Debian amavisd-new at democrasite.com Received: from srv-b.democrasite.com ([127.0.0.1]) by localhost (srv-b.democrasite.com.democrasite.com [127.0.0.1]) (amavisd-new, port 10026) with ESMTP id 5RPAcdHPsOXQ for <[email protected]>; Tue, 27 Oct 2020 11:07:24 +0000 (UTC) Received: from [192.168.1.140] (lneuilly-657-1-64-178.w80-11.abo.wanadoo.fr [80.11.30.178]) (Authenticated sender: [email protected]) by srv-b.democrasite.com (Postfix) with ESMTPSA id 494CF7FC82 for <[email protected]>; Tue, 27 Oct 2020 11:07:24 +0000 (UTC) To: Kameleon Premier <[email protected]> From: opaz-ateliers-contact <[email protected]> Subject: =?UTF-8?Q?test_apr=c3=a8s_security_group_scaleway?= Message-ID: <[email protected]> Date: Tue, 27 Oct 2020 12:07:24 +0100 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:68.0) Gecko/20100101 Thunderbird/68.12.1 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Content-Language: fr test after scaleway security check… I also see that I have one more error : Code: ARC-Authentication-Results: i=1; mx.google.com; dkim=neutral (invalid public key) [email protected] header.s=default header.b=BEIU7955; spf=pass (google.com: domain of [email protected] designates 2001:bc8:47b0:170a::1 as permitted sender) [email protected]; dmarc=pass (p=NONE sp=QUARANTINE dis=NONE) header.from=opaz-ateliers.com
