This page describes all changes made to the ip_app_smtp package, SMTP client, since its release.

Version

2.5 (2017-06-22, 12:22):

2.4 (2017-03-14 09:09):

Values of month and day are converted properly. psp_template_hostname is used.

2.3:

2.2:

Changed psp_get_host_addr() to psp_get_host_domain ( uint8_t * p_domain, uint16_t *p_length ), user needs to define the name of device that is used in hello message.
Outlook SMTP server does not work because it drops TLS connection (probably we use too weak a ciphersuite). Thunderbird SMTP client negotiates Cipher Suite: TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014), which is currently not supported by TLS.

2.1:

Added handling of incoming messages during sending of MAIL content. (Stack was running out of IP buffers because messages were not handled).
Corrected handling of pipeline message for MAIL command (event command_abort was not sent when mail failed).
Added checking of TLS connection state.

Known issues:

Sending of mail to Outlook SMTP servers is difficult, because anti-spam system blocks incoming emails.
Outlook mail account need to have POP server enabled; option POP enable must be set within account settings. In order to turn it on, login to your account, choose Options->'Connect devices and apps with POP' and enable POP
Some SMTP servers (active24) require a correct time to be set in an email. So psp_rtc functions must return a correct date. Gmail/Yahoo/Outlook modifies time in an email.
Timeout test is executed only when no TLS connection is active. This is done because TLS connections are usually tear-down on timeout without notifying the client.
