Re: Notes 12.0 running on IBM i - problems with attachments

Hello Åke

A quick Google revealed that Vipre is a cybersecurity company. When you mention problems sometimes with DOCX or XLSX, I wonder if Vipre has a rule based on the size of attachments - especially about uncompressed size. DOCX and XLSX are compressed archive, basically PKZIP - when you open one in a text editor, the first 2 characters are PK.

We have an application, apparently, that checks for the uncompressed size of ZIP files. It used to treat these Office Open XML (the Microsoft DOCX, etc.) as normal PKZIP and blocked things that should not have.

So the sporadic behavior would happen if Vipre does the same - smaller, no problem, larger, maybe blocked. The size of the DOCX or XLSX does not seem to be a problem, but is you open it with 7-Zip or other such tool, you'll see much larger sizes in the contents.

Anyhow, that's my wild guess based on the behavior you describe, brief as it is.

Cheers
Vern

I have a client (small shop) who (against my initial recommendations)
decided to run their mail server in-house on the IBM i.


The reason I advised against was that the solution would be quite cost
ineffective. But if they feel more at ease with the in house solutions that
is fine by me. And I do love the IBM i but have close to zero detail
knowledge about the inner workings of Notes/Domino!


Now they are having issues with receiving email attachments of type “docx”
and “xslx”. Not always but frequently enough do be a hassle.


I have tried to establish an account to the HCL support forums but for some
reason “OCTA” blocks me.


I know that in house mail on the i is not common but if anyone can hint me
in the right direction that will be most helpful.


OH – for extra details: Customer just told me that the issue may have
something to do with “Vipre” – whatever that is…
