XF 1.5 Server Error Log: Zend_Mail_Transport_Exception

[Drew]

Hello,

All of a sudden I am getting the odd server error logged with regards to Zend Mail.

Emails notifications do see to work fine right now, so this is quite confusing.

Please advise what other info you may need in order to troubleshoot, thanks!

In general, we haven't been able to identify the cause of this particular error ("bad parameters to mail() function"). You can see some discussion of it here: https://xenforo.com/community/threads/server-error-email-not-sent.80013/ The message isn't something I've found in the PHP source so I'm not sure where it's coming from.

I have this exact problem, I am on SiteGround. No idea what to do, there are so many email errors in XenForo error log.
Any ideas?

Most likely it's the MTA configuration that is buggy. Some of the comments that I found in the search for that phrase tend to deal with the sending of HTML messages.
Also found some others that involved a trailing space in the email address.
Another response I found said that this resolved their issue (they were on GoDaddy)

In php.ini for PHP's built-in default is text/hml it was commented out.
;default_charset = "ISO-8859-1" which I uncommented and set to default_charset = "UTF-8" which appeared to solve the problem. I hope that doesn't break something else.

For the php.ini reference, I think he was talking about this setting

default_mimetype = "text/html"

Would be interesting to see if those having issues if they change those two settings it resolves it.
