WARNING: Wide character in print at /usr/share/perl5/PMG/SMTP.pm line 48.

Hello,

We have been noticing this error every time some mail is received that has characters žđščćŽĐŠČĆ in recipient mail.

We are using Mail Gateway 6.3-5 with all latest updates installed.

pmg-smtp-filter[1044]: Wide character in subroutine entry at /usr/share/perl5/PMG/RuleDB/Spam.pm line 138.
pmg-smtp-filter[1044]: WARNING: Wide character in print at /usr/share/perl5/PMG/SMTP.pm line 48.

What we do not understand is why does the mail gateway keep trying to deliver the message if it's "undelivered mail". Should it not refuse the delivery and notify the sender immediately?

Here are the current messages that contain characters žđščćŽĐŠČĆ and are stuck in the queue. Why they are not cleared out immediately once the mail gateway detects 451?
What is the default or RFC time to keep trying to deliver email if 451 is detected?



Let us know how can we fix this.

Thank you!

Hi I've experienced this issue many times in the past, and it starts to be annoying. It looks like this is still not fixed in current version of PMG. Is this such low priority because nobody cares or the solution is somewhat complex? The bug report hasn't been updated for three years now.

We're currently looking into it - so I hope that one of the upcoming versions should contain a fix - but as always - no promises when that will be the case.
