outgoing mail excludes email in "to field

[Matthew Cascio]

On rare occasions, I see failed outgoing mail in the mail queue with the following error:

2024-04-25 13:54:05,099+0000 ERROR [] Sending mailitem To='[NAME REDACTED]' Subject='[SUBJECT REDACTED] ' From='[EMAIL REDACTED]' FromName='' Cc='' Bcc='' ReplyTo='' InReplyTo='null' MimeType='text/plain' Encoding='UTF-8' Multipart='javax.mail.internet.MimeMultipart@ab9a192' MessageId='null' ExcludeSubjectPrefix=true' anonymous    Mail Queue Service [c.a.mail.queue.MailQueueImpl] Error occurred in sending e-mail: To='[NAME REDACTED]' Subject='[SUBJECT REDACTED] ' From='[EMAIL REDACTED] FromName='' Cc='' Bcc='' ReplyTo='' InReplyTo='null' MimeType='text/plain' Encoding='UTF-8' Multipart='javax.mail.internet.MimeMultipart@ab9a192' MessageId='null' ExcludeSubjectPrefix=true'

    ;
      nested exception is:
    	com.sun.mail.smtp.SMTPAddressFailedException: 501 Invalid RCPT TO address provided

The [NAME REDACTED] portion will include only the first name and last name of the recipient - not their email address. 

Anyone else seeing this?

Currently on JSM 5.12.2

P.S. The [EMAIL REDACTED] part does have the correct From email, I just removed it for the purpose of this post.

TIA!

Thanks! Possibly, but I'm looking at the user email and there aren't any special characters.  Will continue to investigate. Thanks for the pointer!
