Email receiving (and sending) broken since 0.8.0-r0 #70

KevinRoebert · 2021-07-29T15:46:56Z

Behaviour

Steps to reproduce this issue

Upgrade from anonaddy/anonaddy:0.7.5 to anonaddy/anonaddy:0.8.0
Receive Mail
Optional: Set ANONADDY_DNS_RESOLVER to any public DNS resolver, e.g., 1.1.1.1 or 8.8.8.8 (Tried with the following settings: 127.0.0.1, 1.1.1.1, 8.8.8.8)
Hostname resolution no longer works. Mails are rejected due to missing reverse hostname resolution.

Expected behaviour

Emails should be able to be received and sent via the "Reply" function. In addition, tIn addition, the name resolution should work.

Actual behaviour

Emails can no longer be received because the name resolution does not work. This also leads to the fact that you can no longer reply to emails that have already been received because the mail does not go directly to the sender, but first via AnonAddy to hide the original email address.

@KevinRoebert Maybe linked to #67. Can you try with anonaddy/anonaddy:test?

@KevinRoebert Maybe linked to #67. Can you try with anonaddy/anonaddy:test?

The error persists even with the anonaddy/anonaddy:test Docker image. The hostnames cannot be resolved. I have attached the log.

I've also tried older images like 0.7.4 and forced a redownload. It works with images < 0.8.0.

@KevinRoebert Ok thanks for your feedback! Might be an issue with Postfix since Alpine 3.14. Will take a look and keep you in touch.

willbrowningme · 2021-07-31T07:34:44Z

Could you try updating your .env file to:

MAIL_FROM_NAME=Example
MAIL_FROM_ADDRESS=mailer@example.com
MAIL_DRIVER=smtp
MAIL_HOST=localhost
MAIL_PORT=25
MAIL_ENCRYPTION=null

See if that sorts it.

crazy-max · 2021-07-31T07:44:07Z

@willbrowningme Don't think that's issue, this is already handled.

crazy-max · 2021-08-01T04:53:48Z

@KevinRoebert I've made some changes in #71, can you try with anonaddy/anonaddy:pr-71? I've also created another image that reverts to Alpine 3.13 with AnonAddy 0.8.0 anonaddy/anonaddy:test-alpine3.13 if you can also try this one. Thanks.

KevinRoebert · 2021-08-02T15:33:17Z

@KevinRoebert Thanks for your feedback! Can you enable POSTFIX_DEBUG with anonaddy/anonaddy:pr-71 and post your logs please?

@willbrowningme I wonder if this is not due to the changes to master.cnf as required by 0.8.0. The config looks good to you?

to:

Imaskiller · 2021-08-05T15:30:05Z

0.8 does not work for me either
in 0.8 i cannot establish a trusted tls connection and thus mail forwarding does not work

but in 0.7.5 the tls conenction works and thus mail forwarding works as well

willbrowningme · 2021-08-06T14:36:28Z

@Imaskiller have you tried changing your .env variables to:

MAIL_HOST=localhost
MAIL_ENCRYPTION=null

This is the only thing I can think it could be.

crazy-max · 2021-08-06T15:05:06Z

@willbrowningme I will make a change and push that. Btw MAIL_HOST=localhost is already enforced.

crazy-max · 2021-08-06T17:15:29Z

@KevinRoebert Can you try with anonaddy/anonaddy:pr-72 (and POSTFIX_DEBUG enabled) please? Thanks!

Nope this does not help either.
I use arm64 and I host it on my home network and reverse lookup fails for my hostname cause of my isp.
This is pretty much the error

willbrowningme · 2021-08-06T17:54:06Z

@Imaskiller it is related to the change from using sendmail to smtp as the Laravel mail driver then.

Could you try updating your /etc/postfix/main.cf file so that you remove reject_unknown_reverse_client_hostname from smtpd_sender_restrictions:

smtpd_sender_restrictions =
   permit_mynetworks
   permit_sasl_authenticated
   reject_non_fqdn_sender
   reject_unknown_sender_domain

   reject_unknown_sender_domain

How do I change it? If i change the file and restart the container i get this error:

/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 794: overriding earlier entry: smtpd_sender_restrictions=permit_mynetworks   permit_sasl_authenticated   reject_non_fqdn_sender   reject_unknown_sender_domain

I also tried volume-binding the changed file but i get the same error and I am not receiving any mails after the change.

@Imaskiller

I also tried volume-binding the changed file but i get the same error and I am not receiving any mails after the change.

Can you try with anonaddy/anonaddy:pr-73?

Unfortunately that still does not fix it. TLS connections cannot be established and ends with the following error in the end:

Aug 07 19:59:17 anonaddy postfix/bounce[966]: warning: 3252811781D: undeliverable postmaster notification discarded,
Aug 07 19:59:17 anonaddy postfix/error[965]: 3252811781D: to=<postmaster@/etc/mailname>, orig_to=<postmaster>, relay=none, delay=0.1, delays=0.04/0.03/0/0.03, dsn=5.1.3, status=bounced (bad address syntax),
Aug 07 19:59:17 anonaddy postfix/qmgr[930]: 3252811781D: removed

I also tried

MAIL_HOST=localhost
MAIL_ENCRYPTION=null

But it fails with the same error in the end.

Edit:
I fixed the TLS issue after renaming my *.pem files to *.crt and *.key
But I cannot reproduce the error for pr-73. Reverse lookup just fails but I dont get the "removed" log anymore.

0.7.5 works still works fine though

crazy-max · 2021-08-08T18:06:00Z

@Imaskiller @KevinRoebert Should be fixed with latest release (0.8.1).

KevinRoebert · 2021-08-08T19:27:20Z

Now there is another error. The log is attached:

@KevinRoebert I've pushed another fix to handle postfix relay restrictions. Can you try with anonaddy/anonaddy:pr-76?

Imaskiller · 2021-08-09T12:05:27Z

@crazy-max same error for me with pr76

Aug 09 12:00:21 anonaddy postfix/smtpd[939]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <***@***>: Relay access denied; from=<***@***> to=<***@***> proto=ESMTP helo=<[127.0.0.1]>

The updated main.cf with in #76

smtpd_relay_restrictions =
    permit_mynetworks,
    permit_sasl_authenticated,
    defer_unauth_destination

Should mean that permit_mynetworks accepts connections from localhost.

Could there be an issue with the current mynetworks vaiable in main.cf? It looks correct to me.

mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16

Or perhaps the fact that the Postfix does not recognise this as a local connection from mynetworks due to the Docker setup?

I can't recreate this issue with a self-hosted instance that was set up manually.

@KevinRoebert I've pushed another fix to handle postfix relay restrictions. Can you try with anonaddy/anonaddy:pr-76?

Does not fix the error. The error message is the same as before.

KevinRoebert · 2021-08-09T18:39:16Z

Docker containers using the private subnet 172.0.0.0/24. Maybe this must be included in mynetworks?
Or is it possible to add a subnet via ENV variable to mynetworks?

crazy-max · 2021-08-09T18:50:39Z

@KevinRoebert @Imaskiller Ok found the issue. Can you docker pull anonaddy/anonaddy:pr-76 and try again please?
