When forwarding an email with with one ZIP attachment (16307 bytes, exported from Thunderbird), OTRS creates an email with two attachments of the same name, (9997 bytes and 4443 bytes). Is this a known problem? Thanks! -- Best regards, Marc Strapetz ============= syntevo GmbH http://www.syntevo.com http://blog.syntevo.com

Do you have logs for that?

I just tried forwarding a large attachment from OTRS and the attachment (3.5MB ZIP) is left intact.

What kind of logs do you refer to? In the system log, there is only one line regarding the forwarded email: " Sent email to ...' from 'syntevo Support '. HistoryType => Forward, Subject => Fwd: Bugreport for SmartSVN; "

...

Where does the "split" occur?

The ZIP file seems to be split. I can forward the same email (received by an OTRS backup account) from my thunderbird over the same SMTP server without any problems. So I think it OTRS itself, not the SMTP server or any other place, where the split occurs. The problem is reproducible. -- Best regards, Marc Strapetz ============= syntevo GmbH http://www.syntevo.com http://blog.syntevo.com On 13.01.2011 16:26, Ralf Hildebrandt wrote:

Can the contents still be unpacked? Or is the ZIP file broken? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt@charite.de | http://www.charite.de

Doesn't look suspicious. Note besides the "xxx" we are also replacing authentication information by "Received: from [127.0.0.1] ..."

The ZIP(s) are both broken and hence Google rejects (see log below).

Interestingly, an attachment with a size of 1.159.960 bytes is split into 95 attachments, all with the same name and same size (10399 bytes), except of the last one (7302 bytes). For every attachment there is also a corresponding file "Part 1.xxx" containing the email's text. -- Best regards, Marc Strapetz ============= syntevo GmbH http://www.syntevo.com http://blog.syntevo.com On 13.01.2011 20:35, Ralf Hildebrandt wrote:

Hi Marc, It's this bug: http://bugs.otrs.org/show_bug.cgi?id=6354 - it only happens if you use the SMTPTLS mail backend. We've already fixed it and the fix will be available in upcoming OTRS 3.0.5 which will become available next Tuesday, if all is well. -- Mike On Fri, Jan 14, 2011 at 11:45 AM, Marc Strapetz wrote:
