Created attachment 8625097 [details] thunderbird_error_screenshot.jpg User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20150525141253 Steps to reproduce: I have email list called !SPAM for spamcop, knujon, etc. AFTER NEWEST UPDATE (it worked ok before) when typed !SPAM it flagged error that email address is incorect. list worked BEFORE Thunderbird update. VERSION: 38.0.1 (up to date) to proceed had to add dummy server name for example !SPAM@test.co.uk where !SPAM is a list name and @test.co.uk is added to pass email address validation. Actual results: failed to send email (error: !spam is not a valid email address...) also copied part of list name to second email address entry field (see screenshot) Expected results: email should have been sent without problems.
I cannot reproduce this. Does this happen with Thunderbird in safe mode?
Hi I have tried: 1. in safe mode - bug still exists 2. after PC reboot - bug still exists Sent email with additional screenshots to confirm the above. Regards Piotr
Hmm, related/dupe of bug 1175900?
Hi. I have found that removing comma from list COMMENT (second, long field) is a workaround so bug could be related to 1175900 but displayed error suggest otherwise (and another workaround which is adding to a name i.e. !SPAM<....,....>) dummy server name (change !SPAM<spam do copa,cert,knujona> --> !SPAM<spam do copa,cert,knujona>@xx.yy)
