Customer using a Groupwise mail server does not get addresses parsed correctly. Consequently mailscanner rejects message as malformed.
Example: joe@mail.com comes in as groupwise-joe@mail.com:1:1 , and thus gets tagged and whacked, returns an undeliverable to sender.
After downgrading to 5.3.3-1 and a permission repair mail is now flowing again.

This is what i see in the message listing, the system is adding that "groupwise-<emailaddress>:1:1 to every email.

04/11/20 11:22:51 vhmatos@emfa.pt groupwise-vitormatos02@gmail.com:1:1

This isn't really a bug but appears to be a violation of RFC on part of Groupwise.

Doing some research. MailScanner is going to need to workaround the violation.

https://info-ims.arnold.narkive.com/GtK ... -extension
https://tools.ietf.org/html/rfc1891
https://tools.ietf.org/html/rfc3461

Yanked from production until we can get this fixed.

Anyone affected...

Just wanted to report the same.

My investigation shows that after receiving mail from Groupwise (if Groupwise has DSN enabled) Mailscanner after scanning tries to pass mail to address found in ORCPT instead in TO.
I temporarily solved issue (have EFA in front of GW) with disabling DSN on Groupwise.
However, If we will get mail from outside Groupwise that has DSN enabled, it will be denied as undeliverable to groupwise-name.surname@mail.com:1:1

I am reporting issue to Microfocus, but anyway if EFA solves it (too) I would appreciate it.

Concerned and interested in what others are seeing. We are running MailScanner 5.3.4 on Postfix as our outer filter and GroupWise 18.2.1 with DSN enabled on GWIA on the inside. GWIA is configured to relay through MailScanner. Checking our Postfix/MailScanner logs, I am not seeing the errors others are. If I filter the log on DSN, I see 62 entries in today's log both inbound and outbound to and from GWIA to MailScanner with the correct email address, no "groupwise-" appended and when I look at the properties of the email I sent today, it says "Transferred" as usual. Both our MailScanner and GW environments are upgrades from old origins though, so there may be things in the config files I have forgotten.

same here

We are using MailScanner in front of Exchange and getting this problem when partners send with Groupwise.
Downgrade MailScanner to 5.3.3 is a workaround.

Do you have DSN enabled on groupwise ?
If you do not, then mail goes as normal. If you do, then you will have problem. So you will have it if someone will send you mail form DSN enabled Groupwise ...

Please update to resolve this issue. I have released 4.0.3-13 to resolve this and other related issues.

Yes as my description indicated, we have DSN enabled and are not seeing this problem.
