Topic: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 0.9.9 PGSQL edition.

I've done a fresh install of a iReadMail-0.9.9 via the downloadable installer. On some of the messages I receive I get errors like this in a /var/log/mail.log file:

I have enabled full query logging in postgres, and here is what the error looks like in Postgres:

Now, this seems like an issue with Amavis that is not compabible with postgres10 that is in Bionic. I will look more into this, but still wanted to share this issue here on the forum (with the hope that someone might already have a solution for this! big_smile )

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

Do you have a sample email which can steadily trigger this error? so that i can test it locally and hopefully fix it.

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

Hi, Zhang. I do, I can email it to you, but it's actually a message from psql-hackers mailing list, this particular one:

https://www.postgresql.org/message-id/a … 815@lancre

The body has funky characters (building that table), but the body is not inserted into the database. When I look trough postgres logs, I see this, again:

So, the first INSERT goes ok. Insert is populating the msgrcpt table, where only bytea column is mail_id.
Field $12 is smtp_resp column, and the value saved there is: "250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 44swGk4PdNzGgb4"

Now, the UPDATE right after updates table msgs. $12 is still that same string as in INSERT, but it is passed to WHERE part of the UPDATE, for mail_id. As mail_id is bytea, postgres won't do conversion from text, and it yields an error.
I see that the mail_id XcZp8EstISXq, which is passed as $2 in the INSERT statement should actually be $12 in the UPDATE satement.

Let me know if you still need the full message file from the mailbox on my server.

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

Hm, actually, what I wrote is not correct. The first list of parameters is related to 'bind' and the second one is related to 'execute'. I don't have the list of UPDATE parameters here.

I will try to hack in extra debugging into amavisd-new and see what exactly causes this postgres issue. It's not happening very often though.

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

Found it!

So, I hacked amavisd to show me parameters of commands being executed. I also noticed that all the errors I get are from emails that have "\dt+'" in subject.

And really, look:

amavisd=# select 'Re: [PATCH v5] Show detailed table persistence in \dt+'::bytea;
ERROR:  invalid input syntax for type bytea
LINE 1: select 'Re: [PATCH v5] Show detailed table persistence in \d...
               ^
amavisd=#


This is postgres10. Happens on xenial with postgres9.5 too, also with postgres11.

It's easy to reproduce this, just send an email that has backslash in the subject, followed by something (like \w, or \dt, or...).

Could you give me a sample subject which can steadily trigger this issue?

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

Any subject that has \  (backslash) in it.

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

I think I fixed this - I changed the column type for msgs.subject from bytea to text, and now I no longer get this error.

When full query is enabled in postgres, now I can see that the UPDATE that was failing before - finishes:

I've also checked amavisd documentation and initialization files, it uses varchar(255) in both postgres and mysql for msgs.sub ject column. Also, I see that with iRedMail some columns are varbinary (mysql) or bytea (postgres), where in upstream amavisd those are vachar.
I see that the change was made to accomodate for Unicode emojis, but I also tried sending an email with emojis in subject, and 'text' colum type treated them as expected:

amavisd=# select subject from msgs where mail_id = 'UJVAglBP4HPf';
                   subject                   
---------------------------------------------
Emoji subject: ð\u009F\u0098\u0088ð\u009F¤ 
(1 row)

Is this ok?

Re: ERROR: invalid input syntax for type bytea (iRedMail-0.9.9 fresh inst

Seems fine. I will try to merge this in next iRedMail release.

But i think this is a bug of Amavisd (PGSQL relevant), could you help try with original Amavisd sql column type and report this to Amavisd mailing list (if you can reproduce it)?
