Mails with embedded images do not fetch

[Diego Ritunnano]

Hello,

I’m having a big problem with Otobo 10.0.15 (not Docker) when it does the fetch of my mail account via IMAPS.

I have already configured a Outlook365 mail account with IMAPS in the system, and it works, as long as the mails do not have any images embedded on its body.

It does not matter how much mails are in the inbox, if any of them has an image embedded, the Daemon starts failing over and over while trying to fetch it, and doesn’t fetch any other mail from inbox, causing our system to being unable to receive mails for some time.

In order to get this working again I use to manually archive those mails, and after fetching the rest of them (often restarting the daemon because it freezes) I try to fetch the mailbox again sending those „image mails“ back to inbox. Sometimes, after a while of opening connections and failing, those mails are fetched, but it would be imposible if I don’t do the previous manual steps.

I have already tried configuring FetchMail, but it throws „There was an error executing /usr/bin/fetchmail -a –ssl: There was a syntax error in the arguments to fetchmail“, and I don’t think that it would solve our problem neither.

Finally, to give you some more information, for testing, the max email size was adjusted to 50MB (although none of the mails received sized more than 3MB), and Otobo seems to be working fine when receiving mails with attachments. It seems that the problem starts when the images are embedded, as I detailed before.

 

Thank you very much for your help, this is urgent for us, because we work a lot with mails and images embedded.

Hi Diego,

strange Problem, I never hear something like that.

We need more information to find the problem. Please can you execute the MailAccountFetch script manually, when a korrupt Mail is given:

root> su - otobo

otobo> bin/otobo.Console.pl Maint::PostMaster::MailAccountFetch --debug

After that please execute:

otobo> bin/otobo.CheckModules.pl --all

And please provide the output of the scripts with more Information about your OS, database and configuration specials here.

I wish you a nice evening,

I have the same issue.

There is no error in mail fetch, but what I noticed was JPG images are fetched without any issues but PNG images are not fetched.

Is there any settings for what type of documents are fetched?

[Pradeep Rajasekaran]

Sorry my bad.

It’s actually the tif images which are not shown.

[Pradeep Rajasekaran]

Although the image is not shown for obvious reason (TIF), it is still there as an attachment but there is no way to download this from OTOBO.

When replying/forwarding the email the TIF file still get attached.

So it would be great to have an option to download/save inline images or convert inline images to attachments.

Hello, we have no problems to open attached Files in Otobo 10.0.15 Docker installation.

Is your file attached or embeddet, example as base64 code?

[Pradeep Rajasekaran]

No problems with attached images.

It is the embedded TIF which are not shown in the browser or shown as an attachment.

Apparently apple (maybe outlook too) allows TIF images to be embedded in emails, but when the emails are fetched into OTOBO, the only way to get those files is to forward it to a different email client which shows the image as an attachment.
