Affects Version/s: 2.6, 2.6.1
Fix Version/s: None
I upgrade to moodle 2.6 and SMTP stopped to work. For example if I try to send mail with email_to_user I get error:
Error: lib/moodlelib.php email_to_user(): SMTP connect() failed.
message in moodle return error:
Error calling message processor email
Search in the forums found this known.
For example: https://moodle.org/mod/forum/discuss.php?d=251703
I replaced current phpmailer with phpmailer of moodle 2.4 and the problem solved.
