Siekiant užtikrinti vartotojų saugumą, POP3/IMAP/SMTP prieiga per pašto programą nėra įjungta kaip numatytoji.

Taip pat, jeigu pageidaujate prisijungti prie pašto programos naudodami POP3/IMAP/SMTP protokolus, turite nustatyti kitą nei Jūsų el.pašto slaptažodį, kurį pamatysite iškart aktyvavę POP3/IMAP prieigą.

Jeigu norite aktyvuoti šį nustatymą:

• Eikite į „Nustatymai“, pasirinkite „Pašto peradresavimas, pašto programos, SMS pranešimai“;
• Varnele pažymėkite „Suteikti išorinio POP3, IMAP ir SMTP prieigą“;
• Po aktyvacijos pamatysite naują slaptažodį naujame lange;
• Nukopijuokite šį slaptažodį ir naudokite jį pasirinktoje pašto programoje.  

Prisiminkite! Automatiškai sugeneruotas slaptažodis nėra nuolatinis ir neskirtas dirbti pašto programoje. Jeigu išjungsite POP3\IMAP\SMTP pašto prieigą arba prieiga bus automatiškai blokuojama jei viršysite siunčiamų laiškų limitą arba bus pasikėsinta pavogti Jūsų paskyrą, tokiu atveju turėsite naudoti naują slaptažodį, kurį gausite iš naujo aktyvavę prieigą.

Dėmesio! Nustatymas „Suteikti išorinio POP3, IMAP ir SMTP prieigą“ gali būti automatiškai išjungtas šiais atvejais:

1. Jeigu sąmoningai pažeidžiate apribojimą siųsti daugiau kaip 15 laiškų per valandą, jeigu naudojatės nemokama Inbox.lt pašto dėžute.
2. Jūsų slaptažodis buvo pavogtas, o Jūsų paskyra pasinaudota spam laiškų siuntimui. Šiuo atveju Jūs nuolat gausite laiškus iš „Mail Delivery System“. Prieš aktyvuojant prieigą, privalėsite pasikeisti naudojamą slaptažodį.
3. Jeigu naudotojo pašto dėžutė gaus statusą „neaktyvi“.
4. Jeigu aktyvus naudotojas daugiau nei 2 mėnesius nesinaudos POP3 prieiga.
5. Jeigu Jūsų pašto programoje bus nustatyti gedimai arba bus viršytas nesėkmingų prisijungimų skaičius.
