I can not change sender mail address

[cezarius]

I change my sender account. Also change field from. When I send test mail I get corrent sender. But when Jira send it automatic (someone write comment) sender still old value but from new account.

Log from mail server:

When press test:

Service: SMTP, From: <noreply@yesprendimai.lt>, To: <info@cezarius.com>, Size: 727, Sender-Host: 127.0.0.1, User: noreply@yesprendimai.lt, Subject: [JIRA] Test Message From JIRA, Msg-Id: <2066399033.7.1524903800253@ns1>

When get automatic:

Service: SMTP, From: <info@yesprendimai.lt>, To: <info@cezarius.com>, Size: 25473, Sender-Host: 127.0.0.1, User: noreply@yesprendimai.lt, Subject: [JIRA] (TAKSI-753) kol neperskaito naujienu neduot paimt uzsakymo, Msg-Id: <JIRA.14803.1524901948000.6.1524902700082@Atlassian.JIRA>

Could you also share with us the rest of the configuration on that page?   Specifically I would want to see the username being used to login to the SMTP server. 

What version of Jira is this?

Have you tried to change the "From address" field, save this, and then immediately restart Jira?  

I suspect that there might be a cache in Jira that is not getting cleared.  However I have not yet found a bug on this.  If this is the case, then changing the value and restarting the application could help because there are a number of caches that will get cleared and rebuilt when the application starts up again.
